Singular perturbations for superlinear problems in non-reflexive fractional Orlicz–Sobolev spaces

Abstract In this work, we investigate the existence and multiplicity as well as regularity of solutions for a huge class of concave–convex problems involving the fractional upper Phi $\Phi$ Φ -Laplacian operator in non-reflexive setting. The main difficulty arises from the lack o...
