The dual Orlicz-Minkowski problem for capillary hypersurfaces

Abstract

We study curvature flows for the dual Orlicz--Minkowski problem for strictly convex capillary hypersurfaces in the Euclidean half-space. The prescribed function has the form $ϕ(h)G(X)$, where $X=\nabla h+hν$ and $G$ may be nonradial and nonhomogeneous. For acute contact angles, the evenness assumption together with either of the two integral conditions yields a smooth weighted-volume-preserving flow for all $t>0$ and a smooth solution to the dual Orlicz--Minkowski equation. Without the evenness assumption, two strict spherical-cap barriers yield the same conclusions for an unnormalized flow, whose limiting hypersurfaces solve the dual Orlicz--Minkowski equation with $c=1$. A uniform strict monotonicity condition under rescaling ensures uniqueness for $c=1$ and convergence of the unnormalized flow in any $C^k$ norm at an exponential rate. The problem considered here includes the capillary $L_p$-Minkowski and $L_p$ dual Minkowski problems as special cases.
