Abstract

We prove that, in a Euclidean domain bounded by hyperplanes having linearly independent normals, a connected oriented compact immersed stable capillary hypersurface \(M^n\) disjoint from the edges of the domain and with the contact angles belonging to \([\pi /2,\pi ]\) must be part of a sphere, if \(\partial M\) is embedded for \(n=2\), or \(\partial M\) is convex in the hyperplane for \(n\ge 3\). By applying a similar argument, we also discuss two other cases where a stable capillary hypersurface must be part of a sphere.
