Jimmy Petean

摘要:

证明了任意n大于4维单连通光滑流形的Yamabe不变量是非负的.等价于流形上所有黎曼度量空间上的数量曲率的L^{n/2}范数的下确界为零。

英文摘要:

We prove that the Yamabe invariant of any simply connected smooth manifold of dimension n greater than four is non-negative. Equivalently that the infimum of the L^{n/2} norm of the scalar curvature, over the space of all Riemannian metrics on the manifold, is zero.
