Abstract
- We investigate here the nonlinear elliptic Hénon-type equation Δ²u =|x|a|u|p-1u in ℝn+ u=∂u/∂xn =0 in ∂ ℝn+, where p > 1, a ≥ 0 and n ≥ 5. Based on the approach of Hu [J. Differential Equations 256 (2014), 1817–1846], we prove Liouville-type theorems for stable solutions and solutions which are stable outside a compact set possibly unbounded and sign-changing. In contrast with the results of Hu (2014), we apply a new method to provide an implicit existence of the fourth-order Joseph– Lundgren exponent. To classify finite Morse index solutions in the supercritical case, we adopt a new method of monotonicity formula together with blowing down sequence. In addition, a difficulty stems from the fact that applying the doubling lemma leads to the singularity. For this reason, we use a more delicate approach to the interval (n + 4 + 2a; pJL2 (n, 0). Our analysis uses a combination of some integral estimates, Pohozaev-type identity, and monotonicity formula of solutions [ABSTRACT FROM AUTHOR]
