We study the Yang-Lee zeros of a random matrix partition function with
the global symmetries of the QCD partition function. We consider both
zeros in the complex chemical potential plane and in the complex mass
plane. In both cases we find that the zeros are located on a curve. I
n the thermodynamic limit, the zeros appear to merge to form a cut. Th
e shape of this limiting curve can be obtained from a saddle-point ana
lysis of the partition function. An explicit solution for the line of
zeros in the complex chemical potential plane at zero mass is given in
the form of a transcendental equation. (C) 1997 Published by Elsevier
