On the classification of capillary graphs in Euclidean and non-Euclidean spaces

We prove some rigidity and classification results for graphs with prescribed mean
curvature and locally constant Dirichlet and Neumann data, for instance as they appear
in capillarity problems. We consider domains in Riemannian manifolds, with emphasis
on R
2
and R
3
. We classify both the underlying domain and the resulting solution,
providing general splitting theorems in this setting.
