A $(ϕ_{n}, ϕ)$ -Poincaré inequality on John domain

Shangying Feng, Tian Liang

Given a bounded domain $Ω \subset R^{n}$ with $n \geq 2$ , let $ϕ$ is a Young function satisfying the doubling condition with the constant $K_{ϕ} < 2^{n}$ . If $Ω$ is a John domain…

A $(ϕ_{\frac{n}{s}}, ϕ)$ -Poincaré inequality in John domain

Shangying Feng, Tian Liang

Let $Ω$ be a bounded domain in $R^{n}$ with $n \geq 2$ and $s \in (0, 1)$ . Assume that $ϕ : [0, \infty) \to [0, \infty)$ be a Young function obeying the doubling condition with the…
