Jeff Streets

摘要:

研究了四维流形上黎曼曲率的$L^2$范数梯度流的低能行为。具体地说,当初始度量具有正的Yamabe常数和小的初始能量时,我们证明了长时间存在性和指数收敛到常截面曲率度量。

英文摘要:

We investigate the low-energy behavior of the gradient flow of the $L^2$ norm of the Riemannian curvature on four-manifolds. Specifically, we show long time existence and exponential convergence to a metric of constant sectional curvature when the initial metric has positive Yamabe constant and small initial energy.
