Existence and Concentration Solutions for a class of elliptic PDEs involving $p$-biharmonic Operator

In this paper, we propose an existence result pertaining to a nontrivial solution to the problem \begin{align*} \Bigg\{\begin{split} & Δ^2_p u -Δ_p u + λV(x)|u|^{p-2}u = f(x,u)\,,\,x\in \mathbb{R}^N, & u \in W^{2,p}(\mathbb{R}^N), \end{split} \end{align*} where $λ>0$, $p>1, N>2p$ and $V\in C(\mathbb{R}^N, \mathbb{R}^+)$, $f\in C(\mathbb{R}^N \times \mathbb{R},\mathbb{R})$ with certain properties. We also investigate the concentration of solutions to the problem on the set $V^{-1}(0)$ as $λ\rightarrow \infty$.

Multiplication operators on Orlicz and weighted Orlicz spaces

Let $(Ω,Σ,μ)$ be a $σ$-finite complete measure space, $τ:Ω\rightarrowΩ$ be a measurable transformation and $ϕ$ be an Orlicz function. In this article, first a necessary and sufficient condition for the bounded multiplication operator $M_u$ on Orlicz space $L^ϕ(Ω)$ induced by measurable function $u$ to be completely continuous has been established. Next by using Radon-Nikodym derivative $ω= \frac{d μ\circ τ^{-1}}{d μ}$, the multiplication operator $M_u$ on weighted Orlicz space $L^ϕ_ω(Ω)$ have been characterized.
