BV-BRST for operator algebras
Abstract: I'll discuss BV-BRST formalism as a useful tool for analyzing algebras of local and extended operators, in topological and/or holomorphic field theories. I'll focus on examples from recent work, including A-infinity/chiral structures on local operators in 3d holomorphic-topological (HT) theories, line operators in 4d HT theories, and cohomological Hall algebras of BPS states.
