本文的目的是证明u t -div形式的非线性抛物方程解的存在性。(a(t,x,u,Du))= H(t,x,u,Du)- div(g(t,x))在Q T = ]0,T[ x Q,Q <$Rn中,初始条件u(0)= u 0,其中u 0是无界的,- div(a(t,x,u,Du))是从Lp(0,T; W1,p0(Ω))到它的对偶的Leray-Lions算子,<$H(t,x,u,Du)<$≤ β <$p + f(t,x),1 < p ≤ N,并且f,g是适当可和的.
The purpose of this paper is to prove the existence of a solution for a nonlinear parabolic equation in the form u t -div(a(t,x,u,Du)) = H(t,x,u,Du) - div(g(t,x)) in Q T = ]0, T[ x Q, Q ⊂ R n , with an initial condition u(0) = u 0 , where u 0 is not bounded, - div(a(t,x,u,Du)) is the usual Leray-Lions operator from L p (0,T;W 1 , p 0 (Ω)) to its dual, ‖H(t,x,u,ξ)‖ ≤ β‖ξ‖ p + f(t,x), 1 < p ≤ N, and f, g are suitably summable.
