In this paper, we estimate the curvature of the Einstein soliton with . We show that the curvature operator is at most polynomial growth if the Ricci curvature is bounded and the volume of the unit ball has a uniform lower bound. Furthermore, for 4 dimensional Einstein soliton, the curvature operator is bounded if the Ricci curvature is bounded.

梯度的曲率估计 爱因斯坦孤子
在本文中,我们估计了 爱因斯坦孤子与 。我们显示,如果Ricci曲率有界且单位球的体积具有统一的下界,则曲率算子最多为多项式增长。此外,对于4维 爱因斯坦孤子,如果Ricci曲率是有界的,则曲率算子是有界的。
