Abstract

In this paper, we investigate further the weighted p(x)p(x)-Hardy inequality with the additional term of the form Ωξp(x)μ1,β(dx)Ωξp(x)μ2,β(dx)+Ωξlogξp(x)μ3,β(dx), \int_\Omega |\xi|^{p(x)}\mu_{1,\beta} (dx) \leqslant \int_\Omega |\nabla \xi|^{p(x)}\mu_{2,\beta} (dx)+\int_\Omega \left|\xi{\log \xi} \right|^{p(x)} \mu_{3,\beta} (dx), holding for Lipschitz functions compactly supported in ΩRn\Omega\subseteq\mathbb{R}^n. The involved measures depend on a certain solution to the partial differential inequality involving p(x)p(x)-Laplacian Δp(x)uΦ{-}\Delta_{p(x)} u\geqslant \Phi, where Φ\Phi is a given locally integrable function, and uu is defined on an open and not necessarily bounded subset ΩRn\Omega\subseteq\mathbb{R}^n , and a certain parameter β\beta. We focus on the nn-dimensional case giving some examples. Moreover, we compare our inequalities with the existing in the literature.
