报告摘要：We describe a novel cohomological approach to identify supersymmetric localizing backgrounds which starts from topological gravity coupled to topological gauge theories.  We apply this topological point of view to N=(2,2) supersymmetric gauge theories in two dimensions, where we found a whole new and unexplored class of localizing supersymmetric backgrounds, which are characterized by non-vanishing fluxes for both the graviphotons of the supergravity multiplet.
