Hochschild Cohomology of Quantum Field Theory

Eli Hawkins, University of York. Part of the algebra seminar series.

After outlining the principles of Algebraic Quantum Field Theory (AQFT) I will describe the generalization of Hochschild cohomology that is relevant to describing deformations in AQFT. An interaction is described by a cohomology class.
