New matrix model solutions to the KacSchwarz problem
Abstract
We examine the KacSchwarz problem of specification of point in Grassmannian in the restricted case of gapone firstorder differential KacSchwarz operators. While the pair of constraints satisfying [ ϰ_{1}, W] = 1 always leads to Kontsevich type models , in the case of [ ϰ_{1}, W] = W the corresponding KP τfunctions are represented as more sophisticated matrix integrals.
