幂零李群上的Ricci Yang-Mills孤子

Ricci Yang-Mills solitons on nilpotent Lie groups

Michael Jablonski, Andrea Young

摘要:

本文的目的是引进幂零李群上的Ricci Yang-Mills孤子方程。在两步幂零条件下,我们证明了这些方程严格弱于Ricci孤子方程。利用几何不变理论中的技巧,我们发展了一种构造不同类型Ricci Yang-Mills孤子的方法。最后,我们给出了不承认Ricci孤子度量但承认Ricci Yang-Mills孤子度量的李群的例子。

英文摘要:

The purpose of this paper is to introduce the Ricci Yang-Mills soliton equations on nilpotent Lie groups. In the 2-step nilpotent setting, we show that these equations are strictly weaker than the Ricci soliton equations. Using techniques from Geometric Invariant Theory, we develop a procedure to build many different kinds of Ricci Yang-Mills solitons. We finish this note by producing examples of Lie groups that do not admit Ricci soliton metrics but that do admit Ricci Yang-Mills soliton metrics.
