Existence results for fractional p-Laplacian problems via Morse theory

Antonio Iannizzotto, Shibo Liu, Kanishka Perera and Marco Squassina


We investigate a class of quasi-linear nonlocal problems, including as a particular case semi-linear problems involving the fractional Laplacian and arising in the framework of continuum mechanics, phase transition phenomena, population dynamics and game theory. Under different growth assumptions on the reaction term, we obtain various existence as well as finite multiplicity results by means of variational and topological methods and, in particular, arguments from Morse theory.
