We assume that Σ = {0} if k = 0 and Σ = ∂Ω if k = N − 1. Let dΣ(x) = dist (x, Σ) and Lµ = Δ + μ d−Σ2, where μ ∈ R. We study boundary value problems (P±) −Lµu ± |u|p−1u = 0 in Ω and trµ,Σ(u) = ν on ∂Ω, where p > 1, ν is a given measure on ∂Ω and trµ,Σ(u) denotes the boundary trace of u associated to Lµ. Different critical exponents for the existence of a solution to (P±) appear according to concentration of ν. The solvability for problem (P+) was proved in [3, 29] in subcritical ranges for p, namely for p smaller than one of the critical exponents. In this paper, assuming the positivity of the first eigenvalue of −Lµ, we provide conditions on ν expressed in terms of capacities for the existence of a (unique) solution to (P+) in supercritical ranges for p, i.e. for p equal or bigger than one of the critical exponents. We also establish various equivalent criteria for the existence of a solution to (P−) under a smallness assumption on ν. ER -
