Generalized Cohomologies and Supersymmetry
Li-Sheng Tseng, Shing-Tung Yau
We show that the complex cohomologies of Bott, Chern, and Aeppli and the symplectic cohomologies of Tseng and Yau arise in the context of type II string theory. Specifically, they…
New Heterotic Non-Kahler Geometries
Melanie Becker, Li-Sheng Tseng, Shing-Tung Yau
New heterotic torsional geometries are constructed as orbifolds of T^2 bundles over K3. The discrete symmetries considered can be freely-acting or have fixed points and/or fixed cu…
Local Heterotic Torsional Models
Ji-Xiang Fu, Li-Sheng Tseng, Shing-Tung Yau
We present a class of smooth supersymmetric heterotic solutions with a non-compact Eguchi-Hanson space. The non-compact geometry is embedded as the base of a six-dimensional non-Ka…
Heterotic Kahler/non-Kahler Transitions
Melanie Becker, Li-Sheng Tseng, Shing-Tung Yau
We show how two topologically distinct spaces - the Kahler K3 x T^2 and the non-Kahler T^2 bundle over K3 - can be smoothly connected in heterotic string theory. The transition occ…
Moduli Space of Torsional Manifolds
Melanie Becker, Li-Sheng Tseng, Shing-Tung Yau
We characterize the geometric moduli of non-Kaehler manifolds with torsion. Heterotic supersymmetric flux compactifications require that the six-dimensional internal manifold be ba…
Anomaly Cancellation and Smooth Non-Kahler Solutions in Heterotic String Theory
Katrin Becker, Melanie Becker, Ji-Xiang Fu +2
We show that six-dimensional backgrounds that are T^2 bundle over a Calabi-Yau two-fold base are consistent smooth solutions of heterotic flux compactifications. We emphasize the i…
