非负曲度量空间与伪合痕

Space of nonnegatively curved metrics and pseudoisotopies

Igor Belegradek, F. Thomas Farrell, Vitali Kapovitch

摘要:

设V是具有完全非负曲度量的开流形,使得灵魂的法球面丛无截面。我们证明了V上邻近的非负曲度量的灵魂是光滑接近的。结合这个结果和伪合痕的一些拓扑性质,我们证明了对许多V,完备非负曲度量空间有无穷多个高阶同伦群。

英文摘要:

Let V be an open manifold with complete nonnegatively curved metric such that the normal sphere bundle to a soul has no section. We prove that the souls of nearby nonnegatively curved metrics on V are smoothly close. Combining this result with some topological properties of pseudoisotopies we show that for many V the space of complete nonnegatively curved metrics has infinite higher homotopy groups.
