Positive Solutions of a Semilinear Elliptic Equation with Singular Dirichlet Boundary Data
Tóm tắt
The purpose of this paper is to construct positive solutions of the semilinear elliptic equation −Δu = up in ℝ+N with a singular Dirichlet boundary condition. We show that for p > (N+1)=(N−1) there exists a positive singular solution which behaves like |x|−2/(p−1) as |x| → 0 and like the Poisson kernel as |x| → ∞.
