Generalized noncooperative Schrödinger-Kirchhoff-type systems in ${\mathbb{R}}^N$

We consider a class of noncooperative Schrödinger-Kirchhoff type system which involves a general variable exponent elliptic operator with critical growth. Under certain suitable conditions on the nonlinearities, we establish the existence of infinitely many solutions for the problem by using the limit index theory, a version of concentration-compactness principle for weighted-variable exponents Sobolev spaces and the principle of symmetric criticality of Krawcewicz and Marzantowicz.
