TITLEMacroscopic loop amplitudes in the multi-cut matrix models

ABSTRACTThe matrix model is known as a non-perturbative formulation of string theory. Recently, the various correspondences between matrix models and string theories have been proposed and the multi-cut matrix model is one of the promising models. In this talk, after giving a brief introduction to matrix model and string theory, we will study the multi-cut matrix models in terms of so-called macroscopic loop amplitudes. In the end of the talk, we will see that macroscopic loop amplitudes in the multi-cut matrix models can be expressed by the Jacobi polynomials in Z_k symmetric background.
