Gauge Invariant Matrix Model for the ÂDÊ Closed Strings
Abstract
The models of triangulated random surfaces embedded in (extended) Dynkin diagrams are formulated as a gaugeinvariant matrix model of Weingarten type. The double scaling limit of this model is described by a collective field theory with nonpolynomial interaction. The propagator in this field theory is essentially twoloop correlator in the corresponding string theory.
