Topological strings from WZW models
We show that the BRST structure of the topological string is encoded in the ``small'' N=4 superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory from hamiltonian reduction of A(1|1). This leads to the important conclusion that not only ordinary string theori...
