Query: On the first eigenvalue for a (p(x),q(x))-Laplacian elliptic system   In this article, we deal about the first eigenvalue for a nonlinear gradient
type elliptic system involving variable exponents growth conditions.
Positivity, boundedness and regularity of associated eigenfunctions for
auxiliaries systems are established.
