Abstract
Let Ω be some open subset of ℝN containing 0 and Ω′=Ω−{0}. If g is a continuous function from ℝ × ℝ into ℝ satisfying some power like growth assumption, then any u∈L ∞loc (Ω′) satisfying
, remains bounded in Ω and satisfies the equation in D'(Ω). We give extensions when the singular set is some compact submanifold of Ω. When g is bounded below on ℝ+ and above on ℝ−, then we prove that any subset Σ with 1-capacity zero is a removable singularity for a function u∈L ∞loc (ω−Σ) satisfying
.
