A critical exponent for Hénon type equation on the hyperbolic space. (English) Zbl 1330.35168
Summary: In this paper, we discuss a critical exponent with respect to the stability of solutions to an Hénon type equation on the hyperbolic space. In Euclidean space, there exists a critical exponent on stable solutions of an Hénon type equation. In particular, this exponent is called the Joseph-Lundgren exponent in case of the Lane-Emden equation. However, on the hyperbolic space, the Lane-Emden equation admits no such critical exponent on stability. We devote this paper to showing the existence of a critical exponent of Joseph-Lundgren type for a weighted Lane-Emden equation. More precisely, we prove non-existence of non-trivial stable solutions of the Hénon type equation for the subcritical case. Moreover, we show that the Hénon type equation has stable, positive, and radial solutions for the supercritical case.
