Boundary behavior of capillary surfaces possibly with extremal boundary angles
For solutions to the capillarity problem possibly with the boundary contact angle θ being 0 and/or π in a relatively open portion of the boundary which is C2, we will show that if the solution is locally bounded up to this portion of boundary, the trace of the solution on this portion is piecewise L...

| Summary: | For solutions to the capillarity problem possibly with the
boundary contact angle θ being 0 and/or π in a relatively open portion of the boundary which is C2, we will show that if the solution is locally bounded up to this portion of
boundary, the trace of the solution on this portion is piecewise
Lipschitz continuous and the solution is Hölder continuous up to
the boundary, provided the prescribed mean curvature is bounded
from above and from below. In the case where θ is not required to be bounded away from π/2, 0, and π, and the mean curvature H(x,t0) belongs to Lp(Ω) for some t0∈ℝ and p>n, under the assumption that in a neighborhood of a relatively open portion of the
boundary the solution is of rotational symmetry, the trace of the solution on
this portion of the boundary is shown to be Hölder continuous with exponent
1/n if n≥3 and with exponent 1/3 if n=2. |
