In this talk, I will discuss positive solutions of equation (E) −Lµu +
uq = 0 in Ω where Ω is a bounded smooth domain in R
N , δ(x) = dist (x, ∂Ω),
Lµ = ∆ + µ
δ
2, µ > 0, q > 1. I will introduce a notion of normalized boundary trace
to obtain a classification of positive solutions of (E) with measure boundary value
in the subcritical case 1 < q < qN,µ. (The critical value qN,µ depends only on N
and µ.) For q ≥ qN,µ, I will show that there exists no solution with an isolated
singularity on the boundary.
