摘要

本文研究了Q \varphi = \varphi Q的三维接触度量流形上的拟Yamabe孤子,证明了如果一个三维接触度量流形M使得Q \varphi = \varphi Q允许具有非零孤子向量场V的拟Yamabe孤子与Reeb向量场{\xi}点线性共线,则V是{\xi}的常数倍,标量曲率为常数,流形为Sasakian。此外,V代表杀戮。最后,我们证明了如果M是一个三维紧致接触流形,使得Q \varphi = \varphi Q具有拟雅贝孤子,则M是平坦的或孤子是平凡的。

Quasi Yamabe Solitons on 3-Dimensional Contact Metric Manifolds with Q\varphi=\varphi Q
In this paper we initiate the study of quasi Yamabe soliton on 3-dimensional contact metric manifold with Q\varphi=\varphi Q and prove that if a 3-dimensional contact metric manifold M such that Q\varphi=\varphi Q admits a quasi Yamabe soliton with non-zero soliton vector field V being point-wise collinear with the Reeb vector field {\xi}, then V is a constant multiple of {\xi}, the scalar curvature is constant and the manifold is Sasakian. Moreover, V is Killing. Finally, we prove that if M is a 3-dimensional compact contact metric manifold such that Q\varphi=\varphi Q endowed with a quasi Yamabe soliton, then either M is flat or soliton is trivial.
