Geometry/Physics Seminar

Title: Vertex algebras, BV master equation and integrable hierarchies
Speaker: Si Li
Speaker Info: Tsinghua University
Brief Description:
Special Note:

We study the effective Batalin-Vilkovisky quantization theory for chiral deformation of two dimensional conformal field theories.

We establish an exact correspondence between renormalized quantum master equations for effective functionals and Maurer-Cartan equations for chiral vertex operators. The generating functions are proven to be almost-holomorphic modular forms.

As an application, we give a universal approach to integrable hierarchies for topological B-models for Calabi-Yau geometries.
