In this letter we show how Wittenâ€™s topological Yang-Mills and gravitational quantum field theories may be obtained by a straightforward BRST gauge fixing procedure. We investigate some aspects ofâ€¦ (More)

A topological procedure for computing correlation functions for any (1, q) model is presented. Our procedure can be used to compute any correlation function on the sphere as well as some correlationâ€¦ (More)

Source Viewer 3D (sv3D) is a software visualization tool, based on a 3D extension of the file map metaphor. Sv3D has been developed as an independent visualization front end that represents sourceâ€¦ (More)

We calculate the supersymmetric type II string partition function in a flat background for the situation where the world-sheet is hyperelliptic. We show explicitly that the contribution to theâ€¦ (More)

-.. -. We show how an SO(2,l) gauge theory with a fermionic symmetry may be used to describe the topology of the moduli space of curves. The observables of the theory correspond to the generators ofâ€¦ (More)
