Month = {December},
url = {http://arxiv.org/abs/1512.07100},
Abstract = {The classical Pfaff-Darboux Theorem, which provides local
normal forms' for 1-forms 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 Pfaff-Darboux 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 n-space, convexity has
its usual meaning. In 2002, Ekeland and Nirenberg were able
to characterize necessary and sufficient conditions for a
given 1-form to admit a convex local normal form (and to
show that some earlier attempts at this characterization had
necessary background, I prove a strengthened and generalized
convex Pfaff-Darboux Theorem, one that covers the case of a
Legendrian foliation in which the notion of convexity is
defined in terms of a torsion-free 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.)},

Abstract = {For smooth manifolds equipped with various geometric

geometric structure is that of a parabolic geometry, our
complexes coincide with the Bernstein-Gelfand-Gelfand
complex associated with the trivial representation. However,
at least in the cases we discuss, our constructions are
relatively simple and avoid most of the machinery of
parabolic geometry. Moreover, our method extends to certain
geometries beyond the parabolic realm.},

class. It can be expressed as a point invariant for a second
order ODE whose integral curves are the geodesics of
$[\Gamma]$ or as a weighted scalar projective invariant of
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 = {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
3-plane fields D on 6-manifolds 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 H-bundle over M where
H is the subgroup of SO(4,3) that stabilizes a null 3-plane
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.},

6-manifolds. A 2-parameter family of intrinsic first-order
functionals on almost complex structures on 6-manifolds is
introduced and their Euler-Lagrange equations are computed.
A natural generalization of holomorphic bundles over complex
manifolds to the almost complex case is introduced. The
general almost complex manifold will not admit any
nontrivial bundles of this type, but there is a class of
nonintegrable almost complex manifolds for which there are
such nontrivial bundles. For example, the G2-invariant
almost complex structure on the 6-sphere admits such
nontrivial bundles. This class of almost complex manifolds
in dimension 6 will be referred to as quasi-integrable and a
corresponding condition for unitary structures is
considered. Some of the properties of quasi-integrable
structures (both almost complex and unitary) are developed
and some examples are given. However, it turns out that
quasi-integrability is not an involutive condition, so the
full generality of these structures in Cartan's sense is not
well-understood. The failure of this involutivity is
discussed and some constructions are made to show, at least
partially, how general these structures can be. © 2006

real-analytic arc A ⊂ ℂ lies in an embedded nonsingular
special Lagrangian submanifold that is SO(n)-invariant. The
same existence result holds for compact A if n = 2. If A is
connected, there exist n distinct nonsingular
SO(n)-invariant special Lagrangian extensions of A such that
any embedded nonsingular SO(n)-invariant special Lagrangian
extension of A agrees with one of these n extensions in some

Abstract = {A second order family of special Lagrangian submanifolds of

satisfaction of a set of pointwise conditions on the second
fundamental form. For example, the set of ruled special
Lagrangian submanifolds of complex 3-space 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 Lawlor-Harvey
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.},

the geometry of G_2-structures on 7-manifolds and is partly

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_2-structure in terms of its torsion. When the fundamental
3-form of the G_2-structure 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 torsion-free. This version contains some new
results on the pinching of Ricci curvature for metrics
associated to closed G_2-structures. 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 long-time existence for given
initial data.},

Abstract = {The motion of a biomolecule greatly depends on the engulfing
solution, which is mostly water. Instead of representing
individual water molecules, it is desirable to develop
implicit solvent models that nevertheless accurately
represent the contribution of the solvent interaction to the
motion. In such models, hydrophobicity is expressed as a
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
space-filling 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
inclusion-exclusion formulas for these sizes.},

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 n-manifold
of constant positive flag curvature out of a hypersurface in
suitably general position in complex projective n-space. The
third remark is that there is a description of the Finsler
metrics of constant curvature on the 2-sphere in terms of a
Riemannian metric and 1-form on the space of its geodesics.
In particular, this allows one to use any (Riemannian) Zoll
metric of positive Gauss curvature on the 2-sphere to
construct a global Finsler metric of constant positive
curvature on the 2-sphere. 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
2n-manifolds. As a by- product, it is found that these
groups do occur as the holonomy of torsion-free affine
connections in dimension 2n, a hitherto unsuspected
phenomenon.&nbsp;},

hypersurfaces in complex space forms of dimension 2 that are
both Levi-flat and minimal. The main results are as follows:
When the curvature of the complex space form is nonzero,
there is a 1-parameter family of such hypersurfaces.
Specifically, for each one-parameter subgroup of the
isometry group of the complex space form, there is an
essentially unique example that is invariant under this
one-parameter subgroup. On the other hand, when the
curvature of the space form is zero, i.e., when the space
form is complex 2-space 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 = {A Kahler metric is said to be Bochner-Kahler 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 Bochner-Kahler metrics in
complex dimension n has real dimension n+1 and a recipe for
an explicit formula for any Bochner-Kahler metric is given.
It is shown that any Bochner-Kahler metric in complex
dimension n has local (real) cohomogeneity at most~n. The
Bochner-Kahler 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 Bochner-Kahler
metric. The fundamental technique is to construct a
canonical infinitesimal torus action on a Bochner-Kahler
metric whose associated momentum mapping has the orbits of
its symmetry pseudo-groupoid as fibers.},

the algebraic cycles in certain extremal homology classes in

deformable only by ambient motions) or quasi-rigid (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.).},

at most 3. The cases where this maximum dimension of
realizability is achieved are analyzed and it is found that
there are two such families of shape operators, one
depending essentially on three arbitrary functions of one
variable and another depending essentially on two arbitrary
functions of one variable. The space of realizations is
discussed in each case, along with some of their remarkable
geometric properties. Several explicit examples are

Abstract = {In this note, we study an overdetermined system of partial
differential equations whose solutions determine the minimal
surfaces in Sn of constant Gaussian curvature. If the
Gaussian curvature is positive, the solution to the global
problem was found by [Calabi], while the solution to the
local problem was found by [Wallach]. The case of
nonpositive Gaussian curvature is more subtle and has
remained open. We prove that there are no minimal surfaces
in Sn of constant negative Gaussian curvature (even
locally). We also find all of the flat minimal surfaces in
Sn and give necessary and sufficient conditions that a given
two-torus may be immersed minimally, conformally, and flatly
into Sn. © 1985 American Mathematical Society.},

Abstract = {A CR-manifold is said to be Lorentzian if its Levi form has
one negative eigenvalue and the rest positive. In this case,
it is possible that the CR-manifold contains holomorphic
curves. In this paper, necessary and sufficient conditions
are derived (in terms of the “derivatives” of the
CR-structure) in order that holomorphic curves exist. A
“flatness” theorem is proven characterizing the real
Lorentzian hyperquadric Qs C CP3and examples are given
showing that nonflat Lorentzian hyperquadrics can have a
richer family of holomorphic curves than the flat ones. ©

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

Month = {December},
url = {http://arxiv.org/abs/1112.2142v2},
Abstract = {For smooth manifolds equipped with various geometric
structures, we construct complexes that replace the de Rham
complex in providing an alternative fine resolution of the
sheaf of locally constant functions. In case that the
geometric structure is that of a parabolic geometry, our
complexes coincide with the Bernstein- Gelfand-Gelfand
complex associated with the trivial representation. However,
at least in the cases we discuss, our constructions are
relatively simple and avoid most of the machinery of
parabolic geometry. Moreover, our method extends to certain
geometries beyond the parabolic realm.},
