Schauder type estimates for degenerate or singular elliptic equations with DMO coefficients

Hongjie Dong, Seongmin Jeon, Stefano Vita

In this paper, we study degenerate or singular elliptic equations in divergence form $$-\text{div}(x_n^{\alpha }A\nabla u)=\text{div}(x_n^{\alpha }\mathbf{g})\text{in }{B}_1\cap \{x_n>0\}.$$ Whe…
