R^{2 m}上具有常Q曲率和大体积的共形度量

Conformal metrics on R^{2m} with constant Q-curvature and large volume

Luca Martinazzi

摘要:

研究了R^{2 m}上具有常Q曲率和有限体积的共形度量。当m=3时,我们证明存在V* 使得对任意V \in [V*,\infty),在R^{6}上存在共形度量g,其中Q_g = S ^{6}的Q-曲率,且vol(g)= V。这与C-S处理的四维情形形成鲜明对比。是林书本文还证明了当$m$是奇数且大于1时,存在一个常数V_m> \vol(S^{2 m}),使得对每个V \in(0,V_m],在R^{2 m}上存在一个共形度量g,其中Q_g = S^{2 m}的Q-曲率,vol(g)= V.这推广了A. Chang和W-X.尘当m为偶数时,我们证明了负Q曲率共形度量的一个类似结果。

英文摘要:

We study conformal metrics on R^{2m} with constant Q-curvature and finite volume. When m=3 we show that there exists V* such that for any V\in [V*,\infty) there is a conformal metric g on R^{6} with Q_g = Q-curvature of S^6, and vol(g)=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\in (0,V_m] there is a conformal metric g on R^{2m} with Q_g = Q-curvature of S^{2m}, 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.
