Geometric transitions and integrable systems
Duiliu-Emanuel Diaconescu, Ron Donagi, Robbert Dijkgraaf +2
We consider {\bf B}-model large duality for a new class of noncompact Calabi-Yau spaces modeled on the neighborhood of a ruled surface in a Calabi-Yau threefold. The closed str…
Geometric Transitions and Mixed Hodge Structures
Duiliu-Emanuel Diaconescu, Ron Donagi, Tony Pantev
We formulate and prove a B-model disc level large N duality result for general conifold transitions between compact Calabi-Yau spaces using degenerations of Hodge structures.
Vector Bundle Extensions, Sheaf Cohomology, and the Heterotic Standard Model
Volker Braun, Yang-Hui He, Burt A. Ovrut +1
Stable, holomorphic vector bundles are constructed on an torus fibered, non-simply connected Calabi-Yau threefold using the method of bundle extensions. Since the manifold is multi…
Notes on gauging noneffective group actions
T. Pantev, E. Sharpe
In this paper we study sigma models in which a noneffective group action has been gauged. Such gauged sigma models turn out to be different from gauged sigma models in which an eff…
A Heterotic Standard Model
Volker Braun, Yang-Hui He, Burt A. Ovrut +1
Within the context of the E_8 x E_8 heterotic superstring compactified on a smooth Calabi-Yau threefold with an SU(4) gauge instanton, we show the existence of simple, realistic N=…
