D-Branes And Mirror Symmetry
TL;DR: In this paper, the authors studied (2,2) supersymmetric field theories on two-dimensional worldsheet with boundaries and determined D-branes (boundary conditions and boundary interactions) that preserve half of the bulk supercharges in nonlinear sigma models.
Journal ArticleDOI
The refined topological vertex
TL;DR: In this paper, a refined topological vertex which depends in addition on a parameter is defined, which physically corresponds to extending the self-dual graviphoton field strength to a more general configuration.

Journal ArticleDOI
Matrix models, geometric engineering and elliptic genera
TL;DR: In this article, the prepotential of = 2 supersymmetric gauge theories in four dimensions was derived by toroidal compactifications of gauge theories from 6 dimensions, as a function of Kahler and complex moduli of T2.
Journal ArticleDOI
Quantum foam and topological strings
TL;DR: In this article, the authors find an interpretation of the recent connection found between topological strings on Calabi-Yau threefolds and crystal melting: summing over statistical mechanical configuration of melting crystal is equivalent to a quantum gravitational path integral involving fluctuations of Kahler geometry and topology.
