Conformal metrics on 2m with constant Q-curvature and large volume
Annales de l'I.H.P. Analyse non linéaire, Tome 30 (2013) no. 6, pp. 969-982.

We study conformal metrics g u =e 2u |dx| 2 on 2m with constant Q-curvature Q g u (2m-1)! (notice that (2m-1)! is the Q-curvature of S 2m ) and finite volume. When m=3 we show that there exists V such that for any V[V ,) there is a conformal metric g u =e 2u |dx| 2 on 6 with Q g u 5! and vol (g u )=V. This is in sharp contrast with the four-dimensional case, treated by C.-S. Lin. We also prove that when m is odd and greater than 1, there is a constant V m > vol (S 2m ) such that for every V(0,V m ] there is a conformal metric g u =e 2u |dx| 2 on 2m with Q g u (2m-1)!, vol (g)=V. This extends a result of A. Chang and W.-X. Chen. When m is even we prove a similar result for conformal metrics of negative Q-curvature.
