Abstract:
In this article, we study nonlinear systems involving several p-Laplacian
operators with variable coefficients. We consider the system
where
denotes the p-Laplacian defined by
with

are given functions;
and the coefficients
(
)
are bounded
smooth positive functions. We prove the existence of
weak solutions defined on bounded and unbounded domains
using the theory of nonlinear monotone operators.
