Abstract

In 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.

  • Non-abelian Hodge theory and higher Teichmüller spaces

    Abstract: Non-abelian Hodge theory relates representations of the fundamental group of a compact Riemann surface X into a Lie group G with holomorphic objects on X known as Higgs bundles, introduced by Hitchin more than 35 years ago. Starting with the case in which G is the circle, and the 19th century Abel-Jacobi's theory, we will move to the case of G=SL(2,R) and the relation to Teichmüller t...

  • Hodge Theory in Combinatorial Geometry

    SpeakerI am interested in the topology of algebraic varieties, and its interaction with combinatorics and algebraic statistics. I am currently interested in the following topics.☑The topological aspects of algebraic optimization problems☑Fourier-Mukai (or Mellin) transformation and the generic vanishing theorems☑Kazhdan-Lusztig theory for matroids☑Schubert varieties of hyperplane arrangemen...
