Vertex algebras, factorization algebras and applications

Session

"Three lines and a bialgebra" by Vadim Schechtman (Univ. of Toulouse)

Description

We will discuss Laplacians and a Lefschetz type decomposition of linear algebra data for perverse sheaves over hyperplane arrangements.
In the factorizable case these objects are closely related to braided bialgebras.

Joint work in progress with M.Kapranov.
