Title: The Batalin-Vilkovisky formalism of the spinning particle
Date: Tue, Dec 01, 2015, 15:30 - 17:00
Place: Seminar Room B
Abstract: We show that the axiom of Felder and Kazhdan on the vanishing of the cohomology groups in negative degree associated to solutions of the classical master equation in the Batalin-Vilkovisky formalism is violated by the spinning particle in a flat background coupled to D=1 supergravity. In this model, there are nontrivial cohomology groups in all negative degrees, regardless of the dimension of the spacetime in which the spinning particle is propagating.
