Abstract
We consider the Dirichlet
problem for the quasilinear elliptic system
-divσ(x,u(x),Du(x))=f on Ω
u(x)=0 on \partialΩ
for a function u:Ω→Rm, where Ω is a bounded open domain in
Rn. For arbitrary right hand side
f∈ W-1,p'(Ω) we prove existence of a weak solution
under classical regularity, growth and coercivity
conditions, but with only very mild monotonicity
assumptions.
