Abstract

A symplectic excision is a symplectomorphism between a manifold and the complement of a closed subset. We focus on the construction of symplectic excisions by Hamiltonian vector fields and give some criteria on the existence and non-existence of such kinds of excisions. The talk is based on arXiv:2101.03534.。

  • A symplectic analogy of Hodge theory I

    AbstractIn analogous to the Hodge theory, Tsai, Tseng and Yau constructed a novel cochain complex on symplectic manifolds, based on the Lefschetz decomposion. Its cohomology is closely related to the de Rham cohomology, but also carries the information of the symplectic form. In the talk we will go through the definition and properties of this cochain complex

  • Symplectic deformations and the Type IIA flow

    Abstract: The equations of flux compactification of Type IIA superstrings were written down by Tomasiello and Tseng-Yau. To study these equations, we introduce a natural geometric flow known as the Type IIA flow on symplectic Calabi-Yau 6-manifolds. We prove the wellposedness of this flow and establish the basic estimates. We show that the Type IIA flow can be applied to find optimal almost com...
