Renormalized Solution for a Class of Doubly Nonlinear Parabolic Obstacle Problems in Orlicz Spaces

M. El Lekhlifi, H. Redwane, M. Rhoudaf, A. Touzani


In this paper, we investigate a class of doubly nonlinear parabolic obstacle problems with L^1-data. The techniques of renormalised solutions are used in Orlicz spaces to prove the existence of a solution.


Nonlinear parabolic equations, Orlicz Sobolev spaces, boundary value problems, truncations, parabolic problems, renormalized solutions.
