可积调和映射问题与Ricci流

The integrable harmonic map problem versus Ricci flow

Sergei L Lukyanov

摘要:

本文构造了一类带Kalb-Ramond项的四参数非线性西格玛模型的零曲率表示。单圈重整化的执行,产生了一组新的古老的和永恒的解决方案的Ricci流扭转。我们的分析提供了一个明确的说明的作用的非线性西格玛模型的重正化的介子场。

英文摘要:

We construct a zero-curvature representation for a four-parameter family of non-linear sigma models with a Kalb-Ramond term. The one-loop renormalization is performed that gives rise to a new set of ancient and eternal solutions to the Ricci flow with torsion. Our analysis provides an explicit illustration of the role of the dilaton field for the renormalization of the non-linear sigma model.
