CORRELATION-FUNCTIONS IN MATRIX MODELS MODIFIED BY WORMHOLE TERMS

We calculate correlation functions in matrix models modified by trace- squared terms. First we study scaling operators in modified one-matrix models and find that their correlation functions satisfy modified Vir asoro constraints. Then we turn to dressed order parameters in minimal models and show that their correlators satisfy Goulian-Li formulae co ntinued to negative Liouville dressing exponents. Our calculations pro vide additional support for the idea that the modified matrix models c ontain operators with the negative branch of gravitational dressing.
