For , by the seminal paper of Brezis and Véron (1980/81), no positive solutions of in exist if . In turn, for the existence and profiles near zero of all positive solutions are given by Friedman and Véron (1986).
In this paper, for every and , we prove that the elliptic problem in with has a solution if and only if , where with . We show that (a) if , then is the only solution of and (b) if , then all solutions of are radially symmetric and their total set is . We give the precise behavior of near zero and at infinity, distinguishing between and , where .
In addition, we answer open questions arising from the works of Cîrstea (2014) and Wei–Du (2017) for by settling the existence and sharp profiles near zero of all positive solutions of in , subject to , where Ω is a smooth bounded domain containing zero.
