Hölder continuity of the gradient at a corner for the capillary problem and related results

Gary M. Lieberman

Vol. 133 (1988), No. 1, 115–135
Abstract

It is well-known that solutions of the capillary problem are smooth when the boundary and contact angle are smooth. Using fairly deep methods which are specific to the capillary problem, Simon and Tam have proved the smoothness of the solution at a corner. Here the smoothness is considered in the context of general nonlinear boundary value problems. The primary tool is a maximum principle argument.
