Multivalued Equations on a Bounded Domain via Minimization on Orlicz-Sobolev Spaces

M. L. Carvalho, J. V. Goncalves

We exploit minimization of locally Lipschitz functionals defined on Orlicz-Sobolev spaces along with convexity techniques, to investigate existence of solution of the multivalued equation

-\Delta_{\Phi} u \in \partial j(.,u) + h − Δ Φ u ∈ ∂ j ( . , u ) + h
in
\Omega Ω
, where
\Omega \subset {\bf R}^N Ω ⊂ R N
is a bounded smooth domain,
\Phi: {\bf R} \to [0,\infty) Φ : R → [ 0 , ∞ )
is an N-function,
\Delta_{\Phi} Δ Φ
is the corresponding
\Phi Φ
-Laplacian,
h h
is a measure on
\Omega Ω
and
\partial j(., u) ∂ j ( . , u )
stands for the Clarke generalized gradient of a function
j j
linked with critical growth. Regularity of the solutions is addressed as well.
