From N=2 Supergravity to Constrained Moduli SpacesDOI: 10.1016/0920-5632(95)00438-F Abstract: In this talk we review some results concerning a mechanism for reducing the moduli space of a topological field theory to a proper submanifold of the ordinary moduli space. Such mechanism is explicitly realized in the example of constrained topological gravity, obtained by topologically twisting the N=2 Liouville theory.
