Abstract

Let ΩRn\Omega\subset \mathbb{R}^n be any open set and uu be a weak supersolution of Lu=c(x)g(u)uu\mathcal{L}u=c(x)g(|u|)\frac{u}{|u|} where Lu(x)=p.v.Rng(u(x)u(y)xys)u(x)u(y)u(x)u(y)K(x,y)dyxys\mathcal{L}u(x)=\text{p.v.} \int_{\mathbb{R}^n} g\left(\frac{|u(x)-u(y)|}{|x-y|^s}\right) \frac{u(x)-u(y)}{|u(x)-u(y)|} K(x,y)\frac{dy}{|x-y|^s} and g=Gg=G^{\prime} for some Young function G.G. This note imparts a Hopf's type lemma and strong minimum principle for uu when c(x)c(x) is continuous in Ωˉ\bar{\Omega} that extend the results of Del Pezzo and Quaas (JDE-2017) in fractional Orlicz-Sobolev setting.
