表面上的Ricci Yang-Mills流

Ricci Yang-Mills flow on surfaces

Jeffrey Streets

摘要:

本文研究了曲面上U(1)丛的Ricci Yang-Mills流的性质。我们表明,存在的流量减少到一个边界上的等周常数。在存在这样一个界限,我们表明,在$S^2$,如果束是非平凡的,流存在的所有时间。对于高亏格曲面,流动始终存在。体积归一化流总是存在的所有时间和收敛到一个常数数量曲率度量与束曲率$F$平行。最后,在附录中,我们分类的表面上的这种流的所有梯度孤子。

英文摘要:

We study the behaviour of the Ricci Yang-Mills flow for U(1) bundles on surfaces. We show that existence for the flow reduces to a bound on the isoperimetric constant. In the presence of such a bound, we show that on $S^2$, if the bundle is nontrivial, the flow exists for all time. For higher genus surfaces the flow always exists for all time. The volume normalized flow always exists for all time and converges to a constant scalar curvature metric with the bundle curvature $F$ parallel. Finally, in an appendix we classify all gradient solitons of this flow on surfaces.
