Constant sign solutions for double phase problems with variable exponents
This article is concerned with quasilinear elliptic equations driven by the variable exponent double phase operators. It also feature parametric terms and a superlinear perturbation. The main result of the article establishes the existence of at least two bounded weak solutions with constant sign. The approach is variational and relies on truncation arguments combined with comparison methods.
