We report two results in topological field theories. Using the Hamiltonian approach, we reinterpret the partition functions of cohomology models as various character-valued indices. Secondly, we also show that, in the presence of Gribov zero modes, the topological field theories without regulating terms permit spontaneous symmetry breaking. The relation to reducible configurations is discussed.
