Existence Results for double phase problem in Sobolev-Orlicz spaces with variable exponents in Complete Manifold

Abstract

In this paper, we study the existence of non-negative non-trivial solutions for a class of double-phase problems where the source term is a Caratheodory function that satisfies the Ambrosetti-Rabinowitz type condition in the framework of Sobolev-Orlicz spaces with variable exponents in complete compact Riemannian n-manifolds. Our approach is based on the Nehari manifold and some variational techniques. Furthermore, the H\"older inequality, continuous and compact embedding results are proved.
