Hölder estimates for elliptic equations degenerate on part of the boundary of a domain
In this paper, the authors consider an elliptic equation which is partially degenerate on the boundary of a domain. The degeneracy is of Keldysh type. By the construction of some barrier functions and the interpolation of the estimates of uniformly elliptic operators, they prove global Hölder estimates when some well-posed boundary conditions are satisfied.
