The present paper deals with a Kirchhoff problem under homogeneous Dirichlet boundary conditions, set in a bounded smooth domain Ω of R^{N}. The problem studied is a stationary version of the orig inal Kirchhoff equation, involving the p(x)-Lap lacian operator, in the framework of the variable exponent Lebesgue and Sobolev spaces. The question of the existence of weak solutions is treated. Appl...

This paper is concerned with the existence of two non-trivial weak solutions for a p(x)-Kirchho type problem by using the mountain pass theorem of Ambrosetti and Rabinowitz and Ekeland's variational principle and the theory of the variable exponent Sobolev spaces.

Abstract We present the theory of a new fractional Sobolev space in complete manifolds with variable exponent. As result, we investigate some our space’s qualitative properties, such as completeness, reflexivity, separability, and density. also show that continuous compact embedding results are valid. apply conclusions this study to variational analysis class $p(z, \cdot )$ <mml:math xmlns:mml=...
