Positive Finite Energy Solutions of Critical Semilinear Elliptic Problems

Abstract
Existence theorems and asymptotic properties will be obtained for boundary value problems of the form in an unbounded domain ΩRN(N ≥3) with smooth boundary, where Δ denotes the TV-dimensional Laplacian, τ — (N+ 2)/ (N — 2) is the critical Sobolev exponent, and is the completion of in the L2(Ω) norm of .
