DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GPRTatNU/51/
 ">General Covariance with Stacks</a>\nby Filip Dul (UMass Amherst) as part
  of Geometry\, Physics\, and Representation Theory Seminar\n\n\nAbstract\n
 General covariance is a crucial notion in the study of field theories on c
 urved spacetimes. In our context\, a generally covariant field theory is o
 ne whose dependence on a Riemannian (or Lorentzian) metric is equivariant 
 with respect to the diffeomorphism group of the underlying manifold/spacet
 ime. In this talk\, we will make these notions precise by using stacks and
  the Batalin-Vilkovisky formalism\, and will moreover recover the associat
 ed equivariant classical observables in the perturbative case.\n
