摘要：
Recently we have introduced a matrix model depending on two coupling constants g(2) and lambda, which contains the fuzzy sphere as a background; to obtain the classical limit g(2) must depend on N in a precise way. In this paper we show how to obtain the classical solitons of the N --> infinity limit imposing the development lambda = (1)/(2) + (lambda0)/(N); as a consequence at finite N one obtains a noncommutative version of the solitons for the fuzzy sphere.
