Abstract

We prove various sharp bounds for the anisotropic pp-capacity CapF,p(K)\mathrm{Cap}_{F,p}(K) (1<p<n1<p<n) of compact sets KK in the Euclidean space Rn\mathbb{R}^n (n3n\geq 3). For example, using the inverse anisotropic mean curvature flow (IAMCF), we get an upper bound of Szeg\"{o} type (1931) for CapF,p(K)\mathrm{Cap}_{F,p}(K) when K\partial K is a smooth, star-shaped and FF-mean convex hypersurface in Rn\mathbb{R}^n (n3n\geq 3). Moreover, for such a surface K\partial K in R3\mathbb{R}^3, by introducing the anisotropic Hawking mass and studying its monotonicity property along IAMCF, we obtain an upper bound of Bray--Miao type (2008) for CapF,p(K)\mathrm{Cap}_{F,p}(K).
