CONCENTRATION PHENOMENA AND COMPETITION EFFECTS FOR FRACTIONAL KIRCHHOFF-CHOQUARD EQUATIONS WITH EXPONENTIAL GROWTH

The Kirchhoff function M(t) = a + bt; a > 0; b > 0, nonlinear function f has the exponential growth, potential functions V and Q are continuous functions satisfying some suitable conditions.
Using Ljusternik-Schnirelmann category theory and variational methods, we establish the multiplicity and concentration of positive solutions for small values of the parameter.
