摘要

In this paper, we are concerned with the fractional order equations (1) with Hartree type (H)over dot(alpha/2)-critical nonlinearity and its equivalent integral equations (3). We first prove a regularity result which indicates that weak solutions are smooth (Theorem 1.2). Then, by applying the method of moving planes in integral forms, we prove that positive solutions u to (1) and (3) are radially symmetric about some point x(0) is an element of R-d and derive the explicit forms for u (Theorem 1.3 and Corollary 1). As a consequence, we also derive the best constants and extremal functions in the corresponding Hardy-Littlewood-Sobolev inequalities (Corollary 2).
