Castellaneta, Diego; Farina, Alberto; Valdinoci, Enrico A pointwise gradient estimate for solutions of singular and degenerate PDE’s in possibly unbounded domains with nonnegative mean curvature. (English) Zbl 1266.35097 Commun. Pure Appl. Anal. 11, No. 5, 1983-2003 (2012). Summary: We consider a singular or degenerate elliptic problem in a proper domain and we prove a gradient bound and some symmetry results.
