*讲座内容简介：
In order to study parallel spinors and related special holonomy metrics, Ammann, Weiss and Witt introduced a spinorial energy functional and investigated its gradient flow. In a joint work with Fei He, we established Berstein-Bando-Shi type estimates for this gradient flow. As applications, we obtained a long time existence criterion and a existence time estimate for the flow.
