摘要

Using Harnack's inequality and a scaling argument we study Liouville-type theorems and the asymptotic behaviour of positive solutions near an isolated singular point zeta is an element of delta Omega U {infinity} for the quasilinear elliptic equation -div(del u(p-2)(A) A del u) + V u(p-2)u = 0 in Omega, where Omega is a domain in R-d, d >= 2, 1 < p < d, and A = (a(ij)) is an element of L-loc(infinity)(Omega; R-dxd) is a symmetric and locally uniformly positive definite matrix. It is assumed that the potential V belongs to a certain Wolff class and has a generalized Fuchsian-type singularity at an isolated point zeta is an element of delta Omega U {infinity}.
