Abstract
In this paper, we consider the following positive solutions of the fractional Hénon equation in :
(Section.Display)
where ,
and
. First, we prove that (1) is equivalent to the following integral equation
(Section.Display)
where is the Green’s function of
in
. Then by combining the method of moving planes in integral forms with a certain type of Kelvin transform, in the subcritical case, we obtain that positive solutions for integral Equation (2) are radially symmetric and monotone decreasing about the origin under some integrability condition.
