【 摘 要 】

We give an existence result of a renormalized solution for a class of nonlinear parabolic equations ∂b(x,u)∂t-div(a(x,t,u,∇u))+g(u)|∇u|p=f, where the right side belongs to L1(Ω × (0,T)), b(x,u) is an unbounded function of u and −div(a(x,t,u,∇u)) is a Leray–Lions type operator with growth ∣∇u∣p−1 in ∇u, but without any growth assumption on u. The function g is just assumed to be continuous on R and satisfying a sign condition.
