摘要：
In this paper we study the following conformally invariant polyharmonic equation Delta(m)u = -u(3+2m/3-2m) in R-3, u > 0, with m = 2, 3. We prove the existence of positive smooth radial solutions with prescribed volume integral(R3) u(6/3-2m) dx. We show that the set of all possible values of the volume is a bounded interval (0,Lambda*] for m = 2, and it is (0,infinity) for m = 3. This is in sharp contrast to m = 1 case in which the volume integral(R3) u(6/3-2m) dx is a fixed value.
