Abstract = {We describe a duality in the moduli space of string vacua
which pairs topologically distinct Calabi-Yau manifolds and
shows that the yield isomorphic conformal theories. At the
level of the geometrical description, this duality
interchanges the roles of Kähler and complex structure
moduli and thus pairs manifolds whose Euler numbers differ
by χ → - χ. Amongst the interesting implications of this
duality is the conclusion that by using both manifolds of a
"mirror pair" the 273 and 273 couplings can be computed
exactly by lowest-order geometrical calculations. ©

Abstract = {We investigate a recently proposed nonperturbative
formulation of two-dimensional quantum gravity coupled to
(p,q) minimal conformal matter. The coupled differential
equations for the partition function summed over topologies
are shown to follow from an action principle. The basic
action for a (p,q) model takes the general form S(p,q) =
∫Res[Qp/q+ 1 + Σk = 0Σα = 0q - 2t(k), αQk + (α +
1)/q], where Q is a qth-order differential operator and the
t(k), α are sources for operator insertions. We illustrate
our results with the explicit examples of the Ising (4,3)
and tricritical Ising (5,4) models. The action S(p,q)
embodies the essential features of the problem (including
the relation to generalized KdV hierarchies) in a most
compact form. © 1990.},

Abstract = {We formulate simple graphical rules which allow explicit
calculation of nonperturbative c = 1 S-matrices. This allows
us to investigate the constraint of nonperturbative
unitarity, which indeed rules out some theories.
Nevertheless, we show that there is an infinite parameter
family of nonperturbatively unitary c = 1 S-matrices. We
investigate the dependence of the S-matrix on one of these
nonperturbative parameters. In particular, we study the
analytic structure, background dependence and high-energy
behavior of some nonperturbative c = 1 S-matrices. The
scattering amplitudes display interesting resonant behavior

Abstract = {We construct a topological Landau-Ginzburg formulation of
the two-dimensional string at the self-dual radius. The
model is an analytic continuation of the Ak+1 minimal model
to k = -3. We compute the superpotential and calculate
tachyon correlators in the Landau-Ginzburg framework. The
results are in complete agreement with matrix model
calculations. We identify the momentum one tachyon as the
puncture operator, non-negative momentum tachyons as primary
fields, and negative momentum ones as descendants. The model
thus has an infinite number of primary fields, and the
topological metric vanishes on the small phase space when
restricted to these. We find a parity invariant
multi-contact algebra with irreducible contact terms of
arbitrarily large number of fields. The formulation of this
Landau-Ginzburg description in terms of period integrals
coincides with the genus zero W1+∞ identities of
two-dimensional string theory. We study the underlying Toda
lattice integrable hierarchy in the Lax formulation and find
that the Landau-Ginzburg superpotential coincides with a
derivative of the Baker-Akhiezer wave function in the
dispersionless limit. This establishes a connection between
the topological and integrable structures. Guided by this
connection we derive relations formally analogous to the
string equation. © 1994.},

Abstract = {We use the gauged linear sigma model introduced by Witten to
calculate instanton expansions for correlation functions in
topological sigma models with target space a toric variety V
or a Calabi-Yau hypersurface M ⊂ V. In the linear model
the instanton moduli spaces are relatively simple objects
and the correlators are explicitly computable; moreover, the
instantons can be summed, leading to explicit solutions for
both kinds of models. In the case of smooth V, our results
reproduce and clarify an algebraic solution of the V model
due to Batyrev. In addition, we find an algebraic relation
determining the solution for M in terms of that for V.
Finally, we propose a modification of the linear model which
computes instanton expansions about any limiting point in
the moduli space. In the smooth case this leads to a
(second) algebraic solution of the M model. We use this
description to prove some conjectures about mirror symmetry,
including the previously conjectured "monomial-divisor
mirror map" of Aspinwall, Greene and Morrison. ©

Abstract = {We describe mirror manifolds in dimensions different from
the familiar case of complex threefolds. We isolate certain
simplifying features present only in dimension three, and
supply alternative methods that do not rely on these special
characteristics and hence can be generalized to other
dimensions. Although the moduli spaces for Calabi-Yau
d-folds are not "special Kähler manifolds" when d>3, they
still have a restricted geometry, and we indicate the new
geometrical structures which arise. We formulate and apply
procedures which allow for the construction of mirror maps
and the calculation of order-by-order instanton corrections
to Yukawa couplings. Mathematically, these corrections are
expected to correspond to calculating Chern classes of
various parameter spaces (Hilbert schemes) for rational
curves on Calabi-Yau manifolds. Our mirror-aided
calculations agree with those Chern class calculations in
the limited number of cases for which the latter can be
carried out with current mathematical tools. Finally, we
make explicit some striking relations between instanton
corrections for various Yukawa couplings, derived from the
associativity of the operator product algebra. © 1995

Abstract = {Superconformal sigma models with Calabi-Yau target spaces

abelian gauge theories in two dimensions. We formulate
mirror symmetry for this class of Calabi-Yau spaces as a
duality in the abelian gauge theory, giving the explicit
mapping relating the two Lagrangians. The duality relates
inequivalent theories which lead to isomorphic theories in
the low-energy limit. This formulation suggests that mirror
symmetry could be derived using abelian duality. The
application of duality in this context is complicated by the
presence of nontrivial dynamics and the absence of a global
symmetry. We propose a way to overcome these obstacles,
leading to a more symmetric Lagrangian. The argument,
however, fails to produce a derivation of the
conjecture.},

the theory flows to N = 1 SUSY QCD. Some of the massless

The new massless states correspond to solitons wrapped about
the collapsing cycles, and their dynamics is described by a
twisted supersymmetric gauge theory on C × R4. We reproduce
this result from an analysis of the S-dual D-manifold. We
check that the predictions made by this model about the
nature of the Higgs branch, the monodromy of period
integrals, and the asymptotics of the one-loop topological
amplitude are in agreement with geometrical computations. In
one of our examples we find that the singularity occurs at

geometry. For the world-volume theory, the analysis of the

Abstract = {We study four N = 1 SU(N)6 gauge theories, with
bi-fundamental chiral matter and a superpotential. In the
infrared, these gauge theories all realize the low-energy
world-volume description of N coincident D3-branes
transverse to the complex cone over a del Pezzo surface dP3
which is the blowup of P2 at three generic points.
Therefore, the four gauge theories are expected to fall into
the same universality class — an example of a phenomenon
that has been termed “toric duality”. However, little
independent evidence has been given that such theories are
infrared-equivalent. In fact, we show that the four gauge
theories are related by the N = 1 duality of Seiberg,
vindicating this expectation. We also study holographic
aspects of these gauge theories. In particular we relate the
spectrum of chiral operators in the gauge theories to
wrapped D3-brane states in the AdS dual description. We
finally demonstrate that the other known examples of toric
duality are related by N = 1 duality, a fact which we
conjecture holds generally.},

Abstract = {We describe a block-spin-like transformation on a simplified
subset of the space of supersymmetric quiver gauge theories
that arise on the worldvolumes of D-brane probes of orbifold
geometries, by sequentially Higgsing the gauge symmetry in
these theories. This process flows to lower worldvolume
energies in the regions of the orbifold moduli space where
the closed string blowup modes, and therefore the
expectation values of the bifundamental scalars, exhibit a
hierarchy of scales. Lifting to the ``upstairs'' matrices of
the image branes makes contact with the matrix
coarse-graining defined in a previous paper. We describe the
structure of flows we observe under this process. The quiver
lattice for $\BC^2/\BZ_N$ in this region of moduli space
deconstructs an inhomogeneous, fractal-like extra dimension,
in terms of which our construction describes a
coarse-graining of the deconstruction lattice.},

configurations, the local transitions extend to extremal

Abstract = {Abstract: We carefully analyze the conditions for an abelian
gauged linear σ-model to exhibit nontrivial IR behavior
described by a nonsingular superconformal field theory
determining a superstring vacuum. This is done without
reference to a geometric phase, by associating singular
behavior to a noncompact space of (semi-)classical vacua. We
find that models determined by reflexive combinatorial data
are nonsingular for generic values of their parameters. This
condition has the pleasant feature that the mirror of a
nonsingular gauged linear σ-model is another such model,
but it is clearly too strong and we provide an example of a
non-reflexive mirror pair. We discuss a weaker condition
inspired by considering extremal transitions, which is also
mirror symmetric and which we conjecture to be sufficient.
We apply these ideas to extremal transitions and to
understanding the way in which both Berglund-Hübsch mirror
symmetry and the Vafa-Witten mirror orbifold with discrete
torsion can be seen as special cases of the general
combinatorial duality of gauged linear σ-models. In the
former case we encounter an example showing that our weaker

three-dimensional theory has a N= 2 SU(N) gauge theory
sector, which we obtain from a twisted dimensional reduction
of a seven-dimensional N= 1 SU(N) gauge theory on the
surface S. A variant of the Vafa–Witten equations governs
the moduli space of the gauge theory, which—for a trivial
SU(N) principal bundle over S—admits a Coulomb and a Higgs
branch. In M-theory these two gauge theory branches arise
from a resolution and a deformation to smooth Calabi–Yau
fourfolds, respectively. We find that the deformed
Calabi–Yau fourfold associated to the Higgs branch
requires for consistency a non-trivial four-form background
flux in M-theory. The flat directions of the flux-induced
superpotential are in agreement with the gauge theory
prediction for the moduli space of the Higgs branch. We
illustrate our findings with explicit examples that realize
the Coulomb and Higgs phase transition in Calabi–Yau

Abstract = {We discuss renormalization group flows in two-dimensional
quantum field theories with (0,2) supersymmetry. We focus on
theories with UV described by a Landau-Ginzburg Lagrangian
and use the chiral algebra to constrain the IR dynamics. We
present examples where the structure of the chiral algebra
is incompatible with unitarity of the IR superconformal
theory and discuss the implications of this result for
programs of classifying (0,2) SCFTs as endpoints of flows
from simple Lagrangian theories.},
