In this paper we consider a nonlinear parabolic problem with a discontinuous, nonmonotone nonlinearity. We assume the existence of an upper solution and a lower solution such that F . Using results from the theory of pseudomonotone operators and from the theory of multivalued analysis together with truncation and penalization techniques, we show that there exists at least one solution Ε½ .

## Abstract In this paper we investigate a nonlinear 1D parabolic problem with algebraicβdifferential boundary conditions. Existence, uniqueness and higher regularity of the solution is proved. It is shown that actually any regularity can be obtained provided that appropriate smoothness of the data
