Morse index versus radial symmetry for fractional Dirichlet problems

Mouhamed Moustapha Fall, Pierre Aime Feulefack, Remi Yvant Temgoua +1

In this work, we provide an estimate of the Morse index of radially symmetric sign changing bounded weak solutions $u$ to the semilinear fractional Dirichlet problem $$ (-Δ)^su = f…
