The Batalin-Vilkovisky (BV) formalism can be seen as a
generalisation of the BRST cohomological methods to handle field
theories with symmetries. In this talk I will give an introduction to
the basics of this formalism, trying to recover what we already know and
hinting at why this is a useful generalisation.

The purpose of this talk is to survey the machinery developed
by Costello, with an emphasis on the procedure by which one starts with
an action functional and ends up with higher algebraic structure at the
end. The running example will take as input the curved beta-gamma
system, a 2d sigma model of maps from a Riemann surface to a complex
manifold. I will sketch how to construct its BV quantization and how to
analyze its factorization algebra, which determines a sheaf of vertex
algebras known as "chiral differential operators." The talk aims to be

If the Batalin-Vilkovisky formalism is a cohomological handle for field theories in the Lagrangian formalism, a similar construction can be set up for the associated Hamiltonian picture and goes under the name of Batalin, Fradkin and Vilkovisky (BFV).
The link between the two has been made explicit recently by Cattaneo, Mnev and Reshetikhin (CMR) as a tool to treat field theories on manifolds with boundary.
In this talk I will review the basics of the BFV and CMR constructions and show how they relate to what we have done so far.
