Abstract
We consider, for a bounded open domain \(\Omega \) in \({{\mathbb {R}}}^{n}\) and a function u: \(\Omega \rightarrow {{\mathbb {R}}}^{m}\), the quasilinear elliptic system
where f belongs to the dual space \(W^{-1,p'}\left( \Omega ,\omega ^{*},{{\mathbb {R}}}^{m}\right) \) of \(W_{0}^{1,p}\left( \Omega ,\omega ,{{\mathbb {R}}}^{m}\right) \). We prove existence of a regularity, growth and coercivity conditions for \(\sigma \), but with only very mild monotonicity.
