Abstract

In this paper, we study the sub-elliptic system ΔλuΔλv=v−p=u−q in RN, (1) where p,q>1 and Δλ is an operator of the form Δλ=∑Ni=1∂xi(λ2i∂xi). We establish some Liouville type results for bounded stable positive solutions of the system. As a consequence, we also obtain a nonexistence result for the scalar equation Δλu=u−p, in RN.
