Abstract:

We consider the following fractional Choquard equation with critical or supercritical growth where s(0,1), μ(0,N), N>2s, q2μ,s, f is a continuous function. It is well-known that 2μ,s=2NμN2s and 2μ,s=2NμN are critical exponents for the above equation in the sense of Hardy-Littlewood-Sobolev inequality. Many existence results have been established for q[2μ,s,2μ,s] in recent years. Here we are interested in critical or supercritical case for the above equation. Under some assumptions of f, the existence and multiplicity of solutions for the above equation can be obtained by applying some analytical techniques.

Key words: Fractional Choquard equation, Critical, Supercritical growth, Truncation technique
