关于流形的谱刻画

On the spectral characterization of manifolds

Alain Connes

摘要:

我们表明,前五个公理,我们制定的谱三元组足够(在一个稍微强的形式),以表征谱三元组光滑紧流形。代数,这是假设是交换的,被证明是同构的代数上的所有光滑函数的唯一光滑导向的紧流形,而运营商被证明是狄拉克型和度量是黎曼。

英文摘要:

We show that the first five of the axioms we had formulated on spectral triples suffice (in a slightly stronger form) to characterize the spectral triples associated to smooth compact manifolds. The algebra, which is assumed to be commutative, is shown to be isomorphic to the algebra of all smooth functions on a unique smooth oriented compact manifold, while the operator is shown to be of Dirac type and the metric to be Riemannian.
