We study conformal metrics gu = e 2udx2 on R2m with constant Qcurvature Qgu ≡ (2m − 1)! (notice that (2m − 1)! is the Qcurvature of S2m) and finite volume. When m = 3 we show that there exists V ∗ such that for any V ∈ [V ∗,∞) there is a conformal metric gu = e 2udx2 on R6 with Qgu ≡ 5! and vol(gu) = V. This is in sharp contrast with the fourdimensional case, treated by CS. Lin. We also prove that when m is odd and greater than 1, there is a constant Vm> vol(S 2m) such that for every V ∈ (0, Vm] there is a conformal metric gu = e 2udx2 on R2m with Qgu ≡ (2m − 1)!, vol(g) = V. This extends a result of A. Chang and WX. Chen. When m is even we prove a similar result for conformal metrics of negative Qcurvature.

"... We study the conformal metrics on R 2m with constant Qcurvature Q ∈ R having finite volume, particularly in the case Q ≤ 0. We show that when Q < 0 such metrics exist in R 2m if and only if m> 1. Moreover we study their asymptotic behavior at infinity, in analogy with the case Q> 0, which ..."

We study the conformal metrics on R 2m with constant Qcurvature Q ∈ R having finite volume, particularly in the case Q ≤ 0. We show that when Q < 0 such metrics exist in R 2m if and only if m> 1. Moreover we study their asymptotic behavior at infinity, in analogy with the case Q> 0, which we treated in a recent paper. When Q = 0, we show that such metrics have the form e 2p g R 2m, where p is a polynomial such that 2 ≤ deg p ≤ 2m − 2 and sup R 2m p < +∞. In dimension 4, such metrics are exactly the polynomials p of degree 2 with limx→+ ∞ p(x) = −∞. 1 Introduction and statement of the main theorems Given a constant Q ∈ R, we consider the solutions to the equation (−∆) m u = Qe 2mu on R 2m, (1) satisfying
