在${\Bbb CP}_2$上的黎曼度量的所有共形类中,Fubini-Study度量的共形类具有最大的Yamabe常数.这个证明涉及到Seiberg-Witten方程的摄动,同时也得到了关于几乎-K\“ahler四维流形的全数量曲率的新结果.
Among all conformal classes of Riemannian metrics on ${\Bbb CP}_2$, that of the Fubini-Study metric is shown to have the largest Yamabe constant. The proof, which involves perturbations of the Seiberg-Witten equations, also yields new results on the total scalar curvature of almost-K\"ahler 4-manifolds.
