Abstract
In a domain \(\Omega \subset {\mathbb {R}}^{n}\) whose boundary is smooth except on a set \({\mathcal {C}}\) of codimension (in \(\partial \Omega \)) k, the behavior of a nonparametric prescribed mean curvature hypersurface \(z=f\left( \mathbf{x}\right) \) in the vertical cylinder \(\Omega \times {\mathbb {R}}\) at a point \({\mathcal {O}}\in {\mathcal {C}}\) can be largely unknown when \(n\ge 3,\) depending on the type of boundary condition f satisfies. In a previous note, the authors considered an example in which \(n=3\) and \(k=2;\) that is, when \({\mathcal {C}}\) is a (nonconvex) conical point on \(\partial \Omega .\) Here, we consider prescribed mean curvature boundary value problems which are rotationally symmetric and investigate the behavior of variational solutions near a point \(P\in {\mathcal {C}}\) when \(n=3\) and \(k=1.\)
