YAU 17, (cis)-isomer

The paper is devoted to the notion of wall-crossing structure and its constructions and applications in various situations. It is… Expand

A bstractWe carry out a systematic analysis of Calabi-Yau threefolds that are elliptically fibered with section (“EFS”) and have… Expand

Gromov-Witten theory is used to define an enumerative geometry of curves in Calabi-Yau 4-folds. The main technique is to find… Expand

Abstract Within the context of the E 8 × E 8 heterotic superstring compactified on a smooth Calabi–Yau threefold with an SU ( 4… Expand

Abstract This is the first of two papers which construct a purely algebraic counterpart to the theory of Gromov–Witten invariants… Expand

We discuss some mathematical conjectures which have come out of the study of Dirichlet branes in superstring theory, focusing on… Expand

We apply ideas that have appeared in the study of D-branes on Calabi-Yau compactifications to the derivation of the BPS spectrum… Expand

Abstract Tests of duality between heterotic strings on K 3 × T 2 (restricted on certain Narain moduli subspaces) and type IIA… Expand

We investigate quantum corrections to the moduli space for hypermultiplets for the type IIA string near a conifold singularity… Expand

Abstract We investigate the compactification of D = 11 supergravity to D = 5,4,3, on compact manifolds of holonomy SU (3) (Calabi… Expand
