Abstract
We give an existence result of the obstacle parabolic equations ∂b(x,u)∂t−div(a(x,t,u,∇u))+div(ϕ(x,t,u))=fin QT, where b(x,u) is bounded function of u, the term −div(a(x,t,u,∇u)) is a Leray-Lions type operator and the function ϕ is a nonlinear lower order and satisfy only the growth condition. The second term f belongs to L1(QT). The proof of an existence solution is based on the penalization methods.
