The collaboration will hold a VIRTUAL meeting on 24-28 May, 2021, entitled “Numerical and Geometric Methods for Ricci-flat Metrics and Flows”.
Bobby Acharya, Robert Bryant, and Jason Lotay.
This workshop will survey some recent progress in understanding methods for constructing, analyzing, and classifying Ricci-flat metrics, Ricci solitons, and various flows. These methods include traditional geometric estimate-based methods as well as numerical approaches to approximating Ricci-flat metrics. There will talks by both mathematicians and physicists and motivations, methods, and applications in physics will be discussed as well.
We will hold two lectures per day, plus moderated discussion sessions on Tuesday and Thursday. Zoom access to the lectures is by invitation only, but YouTube access for the lectures will also be available at
Our schedule is as follows. – All times are given in British Summer Time as well as in Eastern Daylight Time. (Please refer to a time zone converter if you aren’t sure what time it will be in your time zone). There will be a brief conference introduction from Robert Bryant prior to the first talk on Monday.
