Positive Liouville theorem and asymptotic behaviour for \((p,A)\)-Laplacian type elliptic equations with Fuchsian potentials in Morrey space

We study Liouville-type theorems and the asymptotic behaviour of positive solutions near an isolated singular point \(\zeta\in\partial\Omega\cup\{\infty\}\) of the quasilinear elliptic equations $$-\text{div}(|\nabla u|_A^{p-2}A\nabla u)+V|u|^{p-2}u =0\quad\text{in } \Omega\setminus\{\zeta\},$$ where \(\Omega\) is a domain in \(\mathbb{R}^d\) (\(d\geq 2\)), and \(A=(a_{ij})\in L_{\rm loc}^{\infty}(\Omega;\mathbb{R}^{d\times d})\) is a symmetric and locally uniformly positive definite matrix. The potential \(V\) lies in a certain local Morrey space (depending on \(p\)) and has a Fuchsian-type isolated singularity at \(\zeta\).
