正数量曲率与广义Morse函数的解,部分II

Metrics of positive scalar curvature and generalised Morse functions, part II

Mark Walsh

摘要:

Gromov和Lawson的外科手术技术可用于构造由Morse函数参数化的正数量曲率度量族。这对研究光滑流形上正数量曲率度量空间及其相应的模空间起了重要作用。在本文中,我们将这种技术推广到广义莫尔斯函数,即光滑函数与莫尔斯和生灭奇点的家庭工作。

英文摘要:

The surgery technique of Gromov and Lawson may be used to construct families of positive scalar curvature metrics which are parameterised by Morse functions. This has played an important role in the study of the space of metrics of positive scalar curvature on a smooth manifold and its corresponding moduli spaces. In this paper, we extend this technique to work for families of generalised Morse functions, i.e. smooth functions with both Morse and birth-death singularities.
