BIFURCATION RESULTS FOR PROBLEMS WITH FRACTIONAL TRUDINGER-MOSER NONLINEARITY.

By using a suitable topological argument based on cohomological linking and by exploiting a Trudinger{Moser inequality in fractional spaces recently obtained, we prove existence of multiple solutions for a problem in-volving the nonlinear fractional laplacian and a related critical exponential nonlinearity. This extends the literature for the N-Laplacian operator. [ABSTRACT FROM AUTHOR]
