Abstract

We discuss the topological sigma model on an orbifold target space. We describe the moduli space of classical minima for computing correlation functions involving twisted operators, and show, through a detailed computation of an orbifold of CP1 by the dihedral group D4, how to compute the complete ring of observables. Through this procedure, we compute all the rings of dihedral CP1 orbifolds. We then consider CP2/D4, and show how the techniques of topologicalanti-topological fusion might be used to compute twist field correlation functions for nonabelian orbifolds.
