Our main result in this note can be stated as follows: Assume E ⊂ B1 andholds in the C−viscosity sense where |E| = 0 and F is a degenerate elliptic operator. This way, (0.1) holds in the whole unit ball B1 (i.e, E is removable for (0.1)) providedwhere f ∈ L n (B1). Zeroth order term can appear in (0.2) provided u is bounded in B1. This extends a result due to Caffarelli et al. proven in (Commun Pure Appl Math 66(1):109-143, 2013) where a second order linear uniformly elliptic PDE with bounded RHS appeared in place of (0.2).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
