Title:Graded geometry and applications in physics

Reporter:Vladimir Salnikov

Work Unit:CNRS/La Rochelle University

Time:Nov.30-Dec.1,2023

Address:313 Zhengxin Building


Summary of the report:

In this minicourse I will give an overview of results on various instances of graded geometry, that we have obtained with several colleagues in the last years. I will start with a comparison of definitions of N- and Z- graded manifolds and introduce a way of constructing a filtration of the sheaf of function on the latter one. Then I will turn to differential graded manifolds (also called Q-manifolds) and present a normal for result for a homological vector field on Z-graded manifold. Related constructions have been applied in theoretical physics, namely for studying symmetries and gauging of sigma models - I will comment on that. And in the end I will present one of my motivations to going through the labor of all these construction: the problem of integration of differential graded Lie algebras and some ongoing projects inspired by it.
