This paper investigates the ground state solution of the fractional (N/s)-Laplacian Choquard equation. By applying weak growth conditions and refined analysis, the existence of the solution is established, and the concentration phenomenon of the solution is also studied.
This paper is concerned with the following fractional (N/s)-Laplacian Choquard equation: epsilon(N )(-Delta)(s)(N/s)u + V(x)|u|(N/s-2)u = epsilon(mu)(1 / |x|(N-mu )& lowast;F(u) )f(u), x is an element of R-N,where (-Delta)(s)(N/s) denotes the (N/s)-Laplacian operator, 0 < mu < N, and V and f are continuous real functions satisfying some mild assumptions. Applying the weak growth conditions on the exponential critical nonlinearity f and without using the strictly monotone condition, we use some refined analysis and develop the arguments in the existing results to establish the existence of the ground state solution of the fractional (N/s)-Laplacian Choquard equation. Moreover, we also study the concentration phenomenon of the ground state solutions. As far as we know, our results seem to be new concerning the fractional (N/s)-Laplacian equation with the Choquard reaction.
