Liouville theorems for fractional and higher-order Hénon–Hardy systems on ℝn

Abstract

ABSTRACT In this paper, we are concerned with the Hénon–Hardy type systems on : where , , or . We prove Liouville theorems (i.e. non-existence of nontrivial nonnegative solutions) for the above Hénon–Hardy systems. The arguments used in our proof is the method of scaling spheres developed in [Dai W, Qin GLiouville type theorems for fractional and higher-order Hénon–Hardy type equations via the method of scaling spheres. preprint, submitted for publication, arXiv: 1810.02752.]. Our results generalize the Liouville theorems for single Hénon–Hardy equation on in Bidaut-Véron and Pohozaev [Nonexistence results and estimates for some nonlinear elliptic problems.
