Asymptotic behaviour of solutions for a class of degenerate elliptic critical problems Original Research Article

We study the asymptotic behaviour of finite energy solutions to subelliptic equations with critical nonlinearity for the operator L=Δx+|x|2αΔyL=Δx+|x|2αΔy, α>0α>0. In particular, we obtain the exact behaviour at infinity of the related Sobolev extremals.
