Query: Punctures and p-spin curves from matrix models   This article investigates the intersection numbers of the moduli space of
p-spin curves with the help of matrix models. The explicit integral
representations that are derived for the generating functions of these
intersection numbers exhibit p Stokes domains, labelled by a "spin"-component l
taking values l = -1, 0,1,2,...,p-2. Earlier studies concerned integer values
of p, but the present formalism allows one to extend our study to half-integer
or negative values of p, which turn out to describe new types of punctures or
marked points on the Riemann surface. They fall into two classes : Ramond
(l=-1), absent for positive integer p, and Neveu-Schwarz (l\ne -1). The
intersection numbers of both types are computed from the integral
representation of the n-point correlation functions in a large N scaling limit.
We also consider a supersymmetric extension of the random matrix formalism to
show that it leads naturally to an additional logarithmic potential. Open
boundaries on the surface, or admixtures of R and NS punctures, may be handled
by this extension.
