Fundamental Solution of the Laplacian in R^n (n\ge 3)
theoremAnalysisPDEthm:pde-fundamental-solution-laplacian-rn-2026aFor n\ge 3, define \Phi(x)=\frac{1}{n(n-2)\alpha(n)}|x|^{2-n} for x\neq 0, where \alpha(n) is the volume of the unit ball in \mathbb{R}^n. Then -\Delta \Phi = \delta_0 in the sense of distributions.
