摘要
<正> In this paper we discuss the following nonlinear degenerate parabolic systems ui=△ai(ui)+bi(x,t,ui)Dui+fi(x,t,u)for i = 1,2, …, m and u = (u1,…, um) is a vector function, with Dirichlet boundary condition. Under some structure conditions on ai,bi and fi and initial data ui~o∈Li(Ω) for some pi>pi~o = 1,2,…,m, the result on existence and uniquence of global solution is established.
