Abstract

A complete classification of all rotationally invariant operators of the two-dimensional unitary matrix model composed of gradients of the fieldQ and their anomalous dimensions are given in one-loop order. Similarly as in the orthogonal case and for then-vector model the leading correction of operators with2n factors δQ grows withn(n−1).
