一类定常梯度Ricci孤子的数量曲率的一个尖锐下界

A sharp lower bound for the scalar curvature of certain steady gradient Ricci solitons

Manuel Fernandez-Lopez, Eduardo Garcia-Rio

摘要:

证明了当Ricci张量的平方范数与数量曲率的平方之比为1/2时,稳定梯度Ricci孤子的数量曲率由距离不动点的1/2距离函数的双曲正割自下而上有界.

英文摘要:

We show that the scalar curvature of a steady gradient Ricci soliton satisfying that the ratio between the square norm of the Ricci tensor and the square of the scalar curvature is bounded by one half, is boundend from below by the hyperbolic secant of one half the distance function from a fixed point.
