Hamiltonian symmetries and reduction in generalized geometry

Shengda Hu

A closed 3-form $H \in Ω_{0}^{3} (M)$ defines an extension of $Γ (T M)$ by $Ω_{0}^{2} (M)$ . This fact leads to the definition of the group of $H$ -twisted Hamiltonian symmetries $\Ham(M, \JJ; H…

A deRham model for Chen-Ruan cohomology ring of abelian orbifolds

Bohui Chen, Shengda Hu

We present a deRham model for Chen-Ruan cohomology ring of abelian orbifolds. We introduce the notion of \emph{twist factors} so that formally the stringy cohomology ring can be de…

Semi-Stable Degeneration of Toric Varieties and Their Hypersurfaces

Shengda Hu

We provide a construction of examples of semistable degeneration via toric geometry. The applications include a higher dimensional generalization of classical degeneration of K3 su…
