Quasilinear elliptic problems with general growth and merely integrable, or measure, data

Boundary value problems for a class of quasilinear elliptic equations, with an Orlicz type growth and L1 right-hand side are considered. Both Dirichlet and Neumann problems are contemplated. Existence and uniqueness of generalized solutions, as well as their regularity, are established. The case of measure right-hand sides is also analyzed.
