Stochastic Master Fields

Abstract

We treat the stochastic equation for large N master fields proposed by Greensite and Halpern using a construction of master fields modelled after work of Voiculescu, and show that it contains the same information as the usual factorized Schwinger-Dyson equations.

In this version we added comments on the relation to earlier work of Haan and of Cvitanovic, Lauwers and Scharbach. (We also made minor improvements to the body of the paper.) (20pp. harvmac, 1 figure)
