Title

Symplectic cohomology and duality for the wrapped Fukaya category

Abstract To an exact symplectic manifold M, one can two important Floer-theoretic invariants: symplectic cohomology SH^*(M) and the wrapped Fukaya category W(M). We will explain how, when M contains enough Lagrangians, the natural geometric open-closed string maps between the Hochschild homology of W(M), symplectic cohomology, and the Hochschild cohomology of W(M) are all isomorphisms. The induced isomorphism between Hochschild homology and cohomology is an instance of a new self-duality for the wrapped Fukaya category, a non-compact version of a Calabi-Yau structure.

Title

K-theory virtual fundamental classes for moduli spaces of stable maps

Abstract In this talk, I will propose K-theory virtual fundamental classes for moduli spaces of stable map, based on joint work in progress with Bohui Chen and Jianxun Hu in an attempt to define quantum K-theory for general symplectic manifolds.

Title

Twisted Novikov homology, jump loci and non-abelian Hodge theory

Abstract We begin with a brief introduction to the Novikov homology and circle-valued Morse theory. Then I will explain our joint work with Toshitake Kohno about the applications of the Novikov homology to the jump loci in the homology with local coefficients, in particular on compact Kaehler manifolds.
