Existence and multiplicity for fractional Dirichlet problem with $\gamma (\xi )$-Laplacian equation and Nehari manifold

This paper is divided in two parts. In the first part, we prove coercivity results and minimization of the Euler energy functional. In the second part, we focus on the existence and multiplicity of a positive solution of fractional Dirichlet problem involving the $\gamma (\xi )$-Laplacian equation with non-negative weight functions in ${\mathcal{H}}_{\gamma (\xi )}^{\alpha ,\beta ;\chi }(\mathrm{\Lambda },\mathbb{R})$ using some variational techniques and Nehari manifold.
