Isolated singularities of weak solutions to the Serrin-critical $p$-Laplace equation

We classify isolated singularities of nonnegative weak solutions to the Serrin-critical quasilinear Lane-Emden equation $-Δ_p u=u^{\frac{n(p-1)}{n-p}}$ in $B_1\setminus\{0\}$, where $1<p<n$, $Δ_p$ is the classical $p$-Laplacian operator and $B_1\setminus\{0\}\subset\mathbb{R}^n$ is the punctured uni
