Abstract = {We study (0,2) deformations of a (2,2) supersymmetric gauged
linear sigma model for a Calabi-Yau hypersurface in a Fano
toric variety. In the non-linear sigma model these
correspond to some of the holomorphic deformations of the
tangent bundle on the hypersurface. Combinatorial formulas
are given for the number of these deformations, and we show
that these numbers are exchanged by mirror symmetry in a
subclass of the models. © SISSA 2011.},

Abstract = {We enumerate massless E6 singlets for (0,2)-compactifications
of the heterotic string on a Calabi-Yau threefold with the
\standard embedding" in three distinct ways. In the large
radius limit of the threefold, these singlets count
deformations of the Calabi-Yau together with its tangent
bundle. In the \small-radius" limit we apply Landau-Ginzburg
methods. In the orbifold limit we use a combination of
geometry and free field methods. In general these counts
dier. We show how to identify states between these phases
and how certain states vanish from the massless spectrum as
one deforms the complex structure or Kahler form away from
the Gepner point. The appearance of extra singlets for
particular values of complex structure is explored in all
three pictures, and our results suggest that this does not
depend on the Kähler moduli. © SISSA 2012.},

Abstract = {We introduce a class of (0,2) superconformal field theories
based on hybrid geometries, generalizing various known
constructions. We develop techniques for the computation of
the complete massless spectrum when the theory can be
interpreted as determining a perturbative heterotic string
compactification. We provide evidence for surprising
properties regarding RG flows and IR accidental symmetries
in (0,2) hybrid CFTs. We also study the conditions for
embedding a hybrid theory in a particular class of gauged
linear sigma models. This perspective suggests that our
construction generates models which cannot be realized or
analyzed by previously known methods.},

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)

the relation to generalized KdV hierarchies) in a most

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.},

Abstract = {We consider topology changing transitions for M-theory
compactifications on Calabi-Yau fourfolds with background
G-flux. The local geometry of the transition is generically
a genus g curve of conifold singularities, which engineers a
3d gauge theory with four supercharges, near the
intersection of Coulomb and Higgs branches. We identify a
set of canonical, minimal flux quanta which solve the local
quantization condition on G for a given geometry, including
new solutions in which the flux is neither of horizontal nor
vertical type. A local analysis of the flux superpotential
shows that the potential has flat directions for a subset of
these fluxes and the topologically different phases can be
dynamically connected. For special geometries and background
configurations, the local transitions extend to extremal
transitions between global fourfold compactifications with
flux. By a circle decompactification the M-theory analysis
identifies consistent flux configurations in
four-dimensional F-theory compactifications and flat
directions in the deformation space of branes with bundles.

is performed by toric methods, leading to a structure which

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

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
condition is still not necessary.},

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 = {We study M-theory on a Calabi–Yau fourfold with a smooth
surface S of AN–1 singularities. The resulting
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
fourfolds embedded in weighted projective spaces. We

calculate instanton expansions for correlation functions in
topological sigma models with target space a toric variety V

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

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

arbitrarily large number of fields. The formulation of this

Abstract = {Abstract: We study the stability of heterotic
compactifications described by (0,2) gauged linear sigma
models with respect to worldsheet instanton corrections to
the space-time superpotential following the work of Beasley
and Witten [1]. We show that generic models elude the
vanishing theorem proved there, and may not determine
supersymmetric heterotic vacua. We then construct a subclass
of linear models for which a vanishing theorem holds,
generating an extensive list of consistent heterotic
backgrounds.},

flows and the chiral algebra},

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.},
