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 ofCP
1 by the dihedral groupD
4, how to compute the complete ring of observables. Through this procedure, we compute all the rings of dihedralCP
1 orbifolds. We then considerCP
2/D
4, and show how the techniques of topologicalanti-topological fusion might be used to compute twist field correlation functions for nonabelian orbifolds.Supported in part by Fannie and John Hertz Foundation |
