摘要

Yamabe不变量是光滑紧流形的微分同胚不变量，它是由标准化的Einstein-Hilbert泛函产生的。本文强调了一个引人注目的关于Yamabe不变量的开放问题似乎与静态势和拉普拉斯算子的第一特征值密切相关的方式。

Yamabe Invariants, Homogeneous Spaces, and Rational Complex Surfaces

The Yamabe invariant is a diffeomorphism invariant of smooth compact manifolds that arises from the normalized Einstein-Hilbert functional. This article highlights the manner in which one compelling open problem regarding the Yamabe invariant appears to be closely tied to static potentials and the first eigenvalue of the Laplacian.
