关于Ricci孤子的模空间

On moduli spaces of Ricci solitons

Fabio Podesta', Andrea Spiro

摘要:

研究了紧致流形M上收缩Ricci孤子的形变,推广了经典的爱因斯坦度规形变理论。利用M上所有黎曼度量空间中扭曲切片S_f的适当概念,定义了无穷小孤子形变和局域孤子预模空间.本文证明了S_f x C^infty(M)的一个有限维子流形的存在性,该子流形包含固定收缩Ricci孤子周围的孤子的预模空间作为解析子集.我们定义了孤子刚性,并给出了包含它的准则。

英文摘要:

We study deformations of shrinking Ricci solitons on a compact manifold M, generalising the classical theory of deformations of Einstein metrics. Using appropriate notions of twisted slices S_f inside the space of all Riemannian metrics on M, we define the infinitesimal solitonic deformations and the local solitonic pre-moduli spaces. We prove the existence of a finite dimensional submanifold of S_f x C^infty(M), which contains the pre-moduli space of solitons around a fixed shrinking Ricci soliton as an analytic subset. We define solitonic rigidity and give criteria which imply it.
