Gribov problem, contact terms and Cech-de Rham cohomology in 2D topological gravity
We point out that averages of equivariant observables of 2D topological gravity are not globally defined forms on moduli space, when one uses the functional measure corresponding to the formulation of the theory as a 2D superconformal model. This is shown to be a consequence of the existence of the...
