Abstract
In this paper, we study the fractional Henon-Lane-Emden equation associated with Hardy potential (-Delta)(s)u-gamma vertical bar x vertical bar(-2s) u=vertical bar x vertical bar(a)vertical bar u vertical bar(p-1)u in R-n. Extending the celebrated result of [14], we obtain a classification result on finite Morse index solutions to the fractional elliptic equation above with Hardy potential. In particular, a critical exponent p of Joseph-Lundgren type is derived in the supercritical case studying a Liouville type result for the s-harmonic extension problem.
