Abstract

We study the -point functions of scalar multi-trace operators in the gauge theory with adjacent scalars, such as super Yang-Mills, at tree-level by using finite group methods. We derive a set of formulae of the general -point functions, valid for general and to all orders of . In one formula, the sum over Feynman graphs becomes a topological partition function on with a discrete gauge group, which resembles closed string interactions. In another formula, a new skeleton reduction of Feynman graphs generates connected ribbon graphs, which resembles open string interaction. We define the moduli space from the space of skeleton-reduced graphs in the connected -point function of gauge theory. This moduli space is a proper subset of stratified by the genus, and its top component gives a simple triangulation of .
