In this paper we shall describe some correlation function computations in perturbative heterotic strings that, for example, in certain circumstances can lend themselves to a heterotic generalizationâ€¦ (More)

In this note we explicitly work out the precise relationship between Ext groups and massless modes of D-branes wrapped on complex submanifolds of Calabi-Yau manifolds. Specifically, we explicitlyâ€¦ (More)

In this paper we discuss some examples of abelian gauged linear sigma models realizing twisted derived equivalences between non-birational spaces, and realizing geometries in novel fashions. Examplesâ€¦ (More)

In this paper we discuss correlation functions in certain A-twisted Landau-Ginzburg models. Although B-twisted Landau-Ginzburg models have been discussed extensively in the literature, virtually noâ€¦ (More)

In this paper we outline some aspects of nonabelian gauged linear sigma models. First, we review how partial flag manifolds (generalizing Grassmannians) are described physically by nonabelian gaugedâ€¦ (More)

We formulate QFT on a R/Z2 orbifold, in a manner which is invariant under the Z2 time and space reversal. This is a background with closed time-like curves. It is also relevant for the ellipticâ€¦ (More)

In this paper we study string compactifications on Deligne-Mumford stacks. The basic idea is that all such stacks have presentations to which one can associate gauged sigma models, where the groupâ€¦ (More)

In this short note we shall review some recent work [KS] on certain correlation function calculations in perturbative heterotic strings, generalizing the rational curve counting of the A model toâ€¦ (More)
