关于二步流形上Bismut-Ricci形式的一个注记
A remark on the Bismut-Ricci form on 2-step nilmanifolds
摘要:
本文证明了在具有左不变SKT结构的二步幂零李群上,Bismut-Ricci型的(1,1)-部分是半负定的.作为应用,我们给出了二步零流形上不存在不变SKT静态度量和二步零流形上多闭流长时间解的一个简化证明.
英文摘要:
In this note we observe that on a 2-step nilpotent Lie group equipped with a left-invariant SKT structure the (1,1)-part of the Bismut-Ricci form is seminegative definite. As application we give a simplified proof of the non-existence of invariant SKT static metrics on 2-step nilmanifolds and of the existence of a long time solution to the pluriclosed flow in 2-step nilmanifolds.
