摘要：

We study 't Hooft's integral equation determining the meson masses M-n in multicolor QCD(2). In this paper we concentrate on developing an analytic method, and restrict our attention to the special case of quark masses m(1) = m(2) = g/root pi. Among our results is the systematic large-n expansion, and exact sum rules for M-n. Although we explicitly discuss only the special case, the method applies to the general case of quark masses, and we announce some preliminary results for m(1) = m(2) (equations (6.1) and (6.3)).
