The Anisotropic Capillary $L_p$-Minkowski Problem

Abstract

This paper introduces the \textit{anisotropic $ω_0$-capillary $p$-sum} of two hypersurfaces in $\mathbb{R}_+^{n+1}$, and establishes a theory for anisotropic capillary convex bodies. For a smooth convex hypersurface $Σ$ with anisotropic $ω_0$-capillary boundary, we compute the variation of its anisotropic capillary $k$-th quermassintegral via this $p$-sum, thereby defining the associated anisotropic $ω_0$-capillary $k$-th $p$-surface area measure on the capillary Wulff shape $\mathcal{C}_{ω_{0}}$. This motivates us to propose and solve the anisotropic capillary $L_{p}$-Minkowski problem for $p\geq1$.
