摘要
In this paper we are concerned with the following nonlinear degenerate parabolic systems u_t=△x(gradψ(u))+D_xb(u)+f(x.t.u)with Dirichlet boundary conditions,where u,gradψ(u),b and f are vector valued functions and xUnder some structure conditions on the terms of the systems,we have established theresults on existence and uniquence of global solutions of the systems.
In this paper we are concerned with the following nonlinear degenerate parabolic systems ut=△x(grad (u))+Dxb(u)+f (x. t. u)with Dirichlet boundary conditions,where Uvgrad p(u),b and f are vector valued functions and x RN. Under some structure conditions on the terms of the systems, we have established the results on existence and uniquence of global solutions of the systems.
