T-duality invariance in random lattice strings

Abstract

Preserving the T-duality invariance of the continuum string in its random lattice regularization uniquely determines the random matrix model potential. For D=0 the duality transformation can be performed explicitly on the matrix action, and replaces color with flavor; invariance thus requires that the color and flavor groups be the same.
