Abstract

In this article, we show the existence of a unique entropy solution to the following problem: \begin{equation} \begin{split} (-\Delta)_{p,\alpha}^su&= f(x)h(u)+g(x) ~\text{in}~\Omega,\\ u&>0~\text{in}~\Omega,\\ u&= 0~\text{in}~\mathbb{R}^N\setminus\Omega,\nonumber \end{split} \end{equation} where the domain ΩRN\Omega\subset \mathbb{R}^N is bounded and contains the origin, α[0,Nps2) \alpha\in[0,\frac{N-ps}{2}), s(0,1)s\in (0,1), 2sN<p<2-\frac{s}{N}<p<\infty, sp<Nsp<N, gL1(Ω)g\in L^1(\Omega), fLq(Ω)f\in L^q(\Omega) for q>1q>1 and hh is a general singular function with singularity at 0. Further, the fractional pp-Laplacian with weight α\alpha is given by (Δ)p,αsu(x)=P. V.RNu(x)u(y)p2(u(x)u(y))xyN+psdyxαyα, xRN.(-\Delta)_{p,\alpha}^su(x)=\text{P. V.}\int_{\mathbb{R}^N}\frac{|u(x)-u(y)|^{p-2}(u(x)-u(y))}{|x-y|^{N+ps}}\frac{dy}{|x|^\alpha|y|^{\alpha}},~\forall x\in \mathbb{R}^N.
