Abstract: I will present the cohomology theory and deformation theory of grading-restricted vertex algebras developed by myself from 2010 to now. I will start with basic definitions of vertex (operator) algebras and their modules and will give the motivations for the developments of these theories.
Plan: First and second cohomologies of grading-restricted vertex algebras. Extensions and first order deformations of grading-restricted vertex algebras.
