WebWe study the double scaling limit of orthogonal polynomials arising in matrix models of 2D gravity. These "Baker-Akhiezer functions" satisfy linear differential equations whose compatibility conditions are the string and KP flow equations. Moreover, these functions may be interpreted as two-point functions for a 2D field theory on the … WebWe consider the double-scaling limit in the hermitian matrix model for 2D quantum gravity associated with the measure expsumlimits_{j = 1}^N {t_{j^{Z^{2j,} } } N ≥q 3} . We show that after the appropriate modification of the contour of integration the Cross-Migdal-Douglas-Shenker limit to the Painlevé I equation (in the generic case of the pure gravity) is valid …
