heal.abstract	We analyze the double scaling limit of unitary matrix models in terms of trigonometricorthogonal polynomials on the circle. In particular we find a compact formulation of thestring equation at the kthmulticritical point in terms of pseudo-differential operators and acorresponding action principle. We also relate this approach to the mKdV hierarchy whichappears in the analysis in terms of conventional orthogonal polynomials	en
