Abstract

For the homogeneous Dirichlet problem involving a system of equations driven by $(p,q)$-Laplacian operators and general gradient dependence we prove the existence of solutions in the ordered rectangle determined by a subsolution-supersolution. This extends the preceding results based on the method of subsolution-supersolution for systems of elliptic equations. Positive and negative solutions are obtained.

Keywords:

Dirichlet problem,
system of elliptic equations,
$(p,
q)$-Laplacian,
subsolution-supersolution and gradient dependence.
