N=1 SUSY inspired Whitham prepotentials and WDVV

Abstract

This brief review deals with prepotentials inspired by N=1 SUSY considerations due to Cachazo, Intrilligator, Vafa. These prepotentials associated with matrix models following Dijkgraaf and Vafa should be considered as given on an enlarged moduli space that includes Whitham times (couplings of the superpotential). This moduli space is nothing but the whole moduli space of (decorated) hyperelliptic curves. Corresponding prepotentials are logarithms of (quasiclassical) tau-functions and satisfy the WDVV equations.
