Title = {On the convex PfaffDarboux Theorem of Ekeland and
Nirenberg},
Year = {2015},
Month = {December},
url = {http://arxiv.org/abs/1512.07100},
Abstract = {The classical PfaffDarboux Theorem, which provides local
`normal forms' for 1forms on manifolds, has applications in
the theory of certain economic models. However, the normal
forms needed in these models come with an additional
requirement of convexity, which is not provided by the
classical proofs of the PfaffDarboux Theorem. (The
appropriate notion of `convexity' is a feature of the
economic model. In the simplest case, when the economic
model is formulated in a domain in nspace, convexity has
its usual meaning. In 2002, Ekeland and Nirenberg were able
to characterize necessary and sufficient conditions for a
given 1form to admit a convex local normal form (and to
show that some earlier attempts at this characterization had
been unsuccessful). In this article, after providing some
necessary background, I prove a strengthened and generalized
convex PfaffDarboux Theorem, one that covers the case of a
Legendrian foliation in which the notion of convexity is
defined in terms of a torsionfree affine connection on the
underlying manifold. (The main result in Ekeland and
Nirenberg's paper concerns the case in which the affine
connection is flat.)},

the projective class. If the obstruction vanishes we find
the sufficient conditions for the existence of a metric in
the real analytic case. In the generic case they are
expressed by the vanishing of two invariants of order 6 in
the connection. In degenerate cases the sufficient
obstruction is of order at most 8.},

Abstract = {This article is mostly a writeup of two talks, the first
given in the Besse Seminar at the Ecole Polytechnique in
1998 and the second given at the 2000 International Congress
on Differential Geometry in memory of Alfred Gray in Bilbao,
Spain. It begins with a discussion of basic geometry of
almost complex 6manifolds. In particular, I define a 2
parameter family of intrinsic firstorder functionals on
almost complex structures on 6manifolds and compute their
EulerLagrange equations. It also includes a discussion of a
natural generalization of holomorphic bundles over complex
manifolds to the almost complex case. The general almost
complex manifold will not admit any nontrivial bundles of
this type, but there is a large class of nonintegrable
almost complex manifolds for which there are such nontrivial
bundles. For example, the standard almost complex structure
on the 6sphere admits such nontrivial bundles. This class
of almost complex manifolds in dimension 6 will be referred
to as quasiintegrable. Some of the properties of
quasiintegrable structures (both almost complex and
unitary) are developed and some examples are given. However,
it turns out that quasiintegrability is not an involutive
condition, so the full generality of these structures in
Cartan's sense is not wellunderstood.},

Abstract = {The purpose of this note is to provide yet another example
of the link between certain conformal geometries and
ordinary differential equations, along the lines of the
examples discussed by Nurowski in math.DG/0406400. In this
particular case, I consider the equivalence problem for
3plane fields D on 6manifolds M that satisfy the
nondegeneracy condition that D+[D,D]=TM I give a solution of
the equivalence problem for such D (as Tanaka has
previously), showing that it defines a so(4,3) valued
Cartan connection on a principal right Hbundle over M where
H is the subgroup of SO(4,3) that stabilizes a null 3plane
in R^{4,3}. Along the way, I observe that there is
associated to each such D a canonical conformal structure of
split type on M, one that depends on two derivatives of the
plane field D. I show how the primary curvature tensor of
the Cartan connection associated to the equivalence problem
for D can be interpreted as the Weyl curvature of the
associated conformal structure and, moreover, show that the
split conformal structures in dimension 6 that arise in this
fashion are exactly the ones whose so(4,4)valued Cartan
connection admits a reduction to a spin(4,3)connection. I
also discuss how this case has features that are analogous
to those of Nurowski's examples.},

an embedded, noncompact nonsingular realanalytic arc A in C

result holds for compact A if n=2. If A is connected, there
exist n distinct nonsingular SO(n) invariant special

Abstract = {A second order family of special Lagrangian submanifolds of
complex mspace is a family characterized by the
satisfaction of a set of pointwise conditions on the second
fundamental form. For example, the set of ruled special
Lagrangian submanifolds of complex 3space is characterized
by a single algebraic equation on the second fundamental
form. While the `generic' set of such conditions turns out
to be incompatible, i.e., there are no special Lagrangian
submanifolds that satisfy them, there are many interesting
sets of conditions for which the corresponding family is
unexpectedly large. In some cases, these geometrically
defined families can be described explicitly, leading to new
examples of special Lagrangian submanifolds. In other cases,
these conditions characterize already known families in a
new way. For example, the examples of LawlorHarvey
constructed for the solution of the angle conjecture and
recently generalized by Joyce turn out to be a natural and
easily described second order family.},

based on old unpublished joint work with two other people:
F. Reese Harvey and Steven Altschuler. Much of this work has
since been subsumed in the work of Hitchin
\cite{MR02m:53070} and Joyce \cite{MR01k:53093}. I am making
it available now mainly because of interest expressed by
others in seeing these results written up since they do not
seem to have all made it into the literature. A formula is
derived for the scalar curvature and Ricci curvature of a
G_2structure in terms of its torsion. When the fundamental
3form of the G_2structure is closed, this formula implies,
in particular, that the scalar curvature of the underlying
metric is nonpositive and vanishes if and only if the
structure is torsionfree. This version contains some new
results on the pinching of Ricci curvature for metrics
associated to closed G_2structures. Some formulae are
derived for closed solutions of the Laplacian flow that
specify how various related quantities, such as the torsion
and the metric, evolve with the flow. These may be useful in
studying convergence or longtime existence for given
initial data.},

individual water molecules, it is desirable to develop
implicit solvent models that nevertheless accurately

weighted sum of atomic surface areas. The derivatives of
these weighted areas contribute to the force that drives the
motion. In this paper we give formulas for the weighted and
unweighted area derivatives of a molecule modeled as a
spacefilling diagram made up of balls in motion. Other than
the radii and the centers of the balls, the formulas are
given in terms of the sizes of circular arcs of the boundary
and edges of the power diagram. We also give
inclusionexclusion formulas for these sizes.},

Abstract = {The purpose of this article is to classify the real
hypersurfaces in complex space forms of dimension 2 that are
both Leviflat and minimal. The main results are as follows:
When the curvature of the complex space form is nonzero,
there is a 1parameter family of such hypersurfaces.
Specifically, for each oneparameter subgroup of the
isometry group of the complex space form, there is an
essentially unique example that is invariant under this
oneparameter subgroup. On the other hand, when the
curvature of the space form is zero, i.e., when the space
form is complex 2space with its standard flat metric, there
is an additional `exceptional' example that has no
continuous symmetries but is invariant under a lattice of
translations. Up to isometry and homothety, this is the
unique example with no continuous symmetries.},

Abstract = {This article is an exposition of four loosely related
remarks on the geometry of Finsler manifolds with constant
positive flag curvature. The first remark is that there is a
canonical Kahler structure on the space of geodesics of such
a manifold. The second remark is that there is a natural way
to construct a (not necessarily complete) Finsler nmanifold
of constant positive flag curvature out of a hypersurface in
suitably general position in complex projective nspace. The
third remark is that there is a description of the Finsler
metrics of constant curvature on the 2sphere in terms of a
Riemannian metric and 1form on the space of its geodesics.
In particular, this allows one to use any (Riemannian) Zoll
metric of positive Gauss curvature on the 2sphere to
construct a global Finsler metric of constant positive
curvature on the 2sphere. The fourth remark concerns the
generality of the space of (local) Finsler metrics of
constant positive flag curvature in dimension n+1>2 . It is
shown that such metrics depend on n(n+1) arbitrary functions
of n+1 variables and that such metrics naturally correspond
to certain torsion free S^1 x GL(n,R)structures on
2nmanifolds. As a by product, it is found that these
groups do occur as the holonomy of torsionfree affine
connections in dimension 2n, a hitherto unsuspected
phenomenon. },

Month = {March},

Abstract = {I use local differential geometric techniques to prove that
the algebraic cycles in certain extremal homology classes in
Hermitian symmetric spaces are either rigid (i.e.,
deformable only by ambient motions) or quasirigid (roughly
speaking, foliated by rigid subvarieties in a nontrivial
way). These rigidity results have a number of applications:
First, they prove that many subvarieties in Grassmannians
and other Hermitian symmetric spaces cannot be smoothed
(i.e., are not homologous to a smooth subvariety). Second,
they provide characterizations of holomorphic bundles over
compact Kahler manifolds that are generated by their global
sections but that have certain polynomials in their Chern
classes vanish (for example, c_2 = 0, c_1c_2  c_3 = 0, c_3
= 0, etc.).},

Abstract = {The problem of immersing a simply connected surface with a
prescribed shape operator is discussed. From classical and
more recent work, it is known that, aside from some special
degenerate cases, such as when the shape operator can be
realized by a surface with one family of principal curves
being geodesic, the space of such realizations is a convex
set in an affine space of dimension at most 3. The cases
where this maximum dimension of realizability is achieved
have been classified and it is known that there are two such
families of shape operators, one depending essentially on
three arbitrary functions of one variable (called Type I in
this article) and another depending essentially on two
arbitrary functions of one variable (called Type II in this
article). In this article, these classification results are
rederived, with an emphasis on explicit computability of the
space of solutions. It is shown that, for operators of
either type, their realizations by immersions can be
computed by quadrature. Moreover, explicit normal forms for
each can be computed by quadrature together with, in the
case of Type I, by solving a single linear second order ODE
in one variable. (Even this last step can be avoided in most
Type I cases.) The space of realizations is discussed in
each case, along with some of their remarkable geometric
properties. Several explicit examples are constructed
(mostly already in the literature) and used to illustrate
various features of the problem.},

Abstract = {A Kahler metric is said to be BochnerKahler if its Bochner
curvature vanishes. This is a nontrivial condition when the
complex dimension of the underlying manifold is at least 2.
In this article it will be shown that, in a certain well
defined sense, the space of BochnerKahler metrics in
complex dimension n has real dimension n+1 and a recipe for
an explicit formula for any BochnerKahler metric is given.
It is shown that any BochnerKahler metric in complex
dimension n has local (real) cohomogeneity at most~n. The
BochnerKahler metrics that can be `analytically continued'
to a complete metric, free of singularities, are identified.
In particular, it is shown that the only compact Bochner
Kahler manifolds are the discrete quotients of the known
symmetric examples. However, there are compact Bochner
Kahler orbifolds that are not locally symmetric. In fact,
every weighted projective space carries a BochnerKahler
metric. The fundamental technique is to construct a
canonical infinitesimal torus action on a BochnerKahler
metric whose associated momentum mapping has the orbits of
its symmetry pseudogroupoid as fibers.},

local classification for such harmonic morphisms with
specified target metric, the second is a finiteness theorem
for such harmonic morphisms with specified domain metric,
and the third is a complete classification of such harmonic
morphisms when the domain is a space form of constant
sectional curvature. The methods used are exterior
differential systems and the moving frame. The basic results
are local, but, because of the rigidity of the solutions,
they allow a complete global classification.},

first problem is the study of when two minimal graphs can
induce the same area function on the domain without
differing by trivial symmetries. The second problem is
similar but concerns a different `area Lagrangian' first
investigated by Calabi. The third problem classified the
harmonic maps between spheres (more generally, manifolds of
constant sectional curvature) for which the energy density
is a constant multiple of the volume form. In the first and
third cases, the complete solution is described. In the
second case, some information about the solutions is
derived, but the problem is not completely

Abstract = {When can a real hypersurface in complex nspace contain any
complex curves? Since the tangent spaces to such a curve
would have to be null vectors for the Levi form, a necessary
condition is that the Levi form have zeros. The simplest way
this can happen in the nondegenerate case is for the Levi
form to have the Lorentzian signature. In this paper, I show
that a Lorentzian CRmanifold M has at most a finite
parameter family of holomorphic curves, in fact, at most an
n2 parameter family if the dimension of M is 2n+1. This
maximum is attained, as I show by example. When n=2, the
only way it can be reached is for M to be CRflat. In higher
dimensions, where the CRflat model does not achieve the
maximum, it is still unknown whether or not there is more
than one local model with the maximal dimension family of
holomorphic curves. The technique used is exterior
differential systems together with the ChernMoser theory in
the n=2 case. Reprints are available, but can also be
downloaded from the AMS or from JSTOR},

Abstract = {A study of the geometry of submanifolds of real 8space
under the group of motions generated by translations and
rotations in the subgroup Spin(7) instead of the full SO(8).
I call real 8space endowed with this group O or octonian
space. The fact that the stabilizer of an oriented 2plane
in Spin(7) is U(3) implies that any oriented 6manifold in O
inherits a U(3)structure. The first part of the paper
studies the generality of the 6manifolds whose inherited
U(3)structure is symplectic, complex, or Kähler, etc.
by applying the theory of exterior differential systems. I
then turn to the study of the standard 6sphere in O as an
almost complex manifold and study the space of what are now
called pseudoholomorphic curves in the 6sphere. I prove
that every compact Riemann surface occurs as a (possibly
ramified) pseudoholomorphic curve in the 6sphere. I also
show that all of the genus zero pseudoholomorphic curves in
the 6sphere are algebraic as surfaces. Reprints are
available.},
