Matrix factorizations and singularity categories for stacks [PDF]

open access: yes, 2010
We study matrix factorizations of a section W of a line bundle on an algebraic stack. We relate the corresponding derived category (the category of D-branes of type B in the Landau-Ginzburg model with potential W) with the singularity category of the ...

Tautological relations and the r-spin Witten conjecture [PDF]

open access: yes, 2009
In a series of two preprints, Y.-P. Lee studied relations satisfied by all formal Gromov-Witten potentials, as defined by A. Givental. He called them "universal relations" and studied their connection with tautological relations in the cohomology ring of

Stringy orbifolds

open access: yes, 2002
Recently, there is an explosive growth of activities to understand stringy properties of orbifolds. In this article, we survey some of recent developments.Comment: A survery article written for the Proceedings of Workshop on Mathematical Aspect of ...

Some Navigation Rules for D-Brane Monodromy [PDF]

open access: yes, 2001
We explore some aspects of monodromies of D-branes in the Kahler moduli space of Calabi-Yau compactifications. Here a D-brane is viewed as an object of the derived category of coherent sheaves.

A survey on symplectic singularities and resolutions [PDF]

open access: yes, 2005
This is a survey written in an expositional style on the topic of symplectic singularities and symplectic resolutions, which could also serve as an introduction to this ...

Derived Category Automorphisms from Mirror Symmetry

open access: yes, 2004
Inspired by the homological mirror symmetry conjecture of Kontsevich, we construct new classes of automorphisms of the bounded derived category of coherent sheaves on a smooth Calabi-Yau variety.Comment: LaTeX, 27 pages, no figures; substantially revised;

Absolutely trianalytic tori in the generalized Kummer variety [PDF]

open access: yes, 2015
We prove that a generic complex deformation of a generalized Kummer variety contains no complex analytic tori.Comment: 14 pages. Some changes after comments.

A framework for tropical mirror symmetry [PDF]

open access: yes, 2011
Applying tropical geometry a framework for mirror symmetry, including a mirror construction for Calabi-Yau varieties, was proposed by the author. We discuss the conceptual foundations of this construction based on a natural mirror map identifying ...

Factorization of point configurations, cyclic covers and conformal blocks

open access: yes, 2012
We describe a relation between the invariants of $n$ ordered points in $P^d$ and of points contained in a union of linear subspaces $P^{d1}\cup P^{d2} \subset P^d$.

D-brane categories

open access: yes, 2003
This is an exposition of recent progress in the categorical approach to D-brane physics. I discuss the physical underpinnings of the appearance of homotopy categories and triangulated categories of D-branes from a string field theoretic perspective, and ...
