Zakharov Lectureship 2022

We are pleased to announce the "Zakharov Lectureship" in honor of Regents Professor Vladimir Zakharov's retirement, his contributions to the Program in Applied Mathematics and the Mathematics Department.  The event will support an annual series of lectures during the spring in Tucson.  The first Zakharov Lectureship begins on Monday, January 31, 2022 and will be given by distinguished scientist, Professor Gregory Falkovich from the Weizmann Institute of Science.  He will give a series of 5 lectures, once per week over 5 weeks on “Physical Nature of Information: How to receive, send and forget information”.  Please see schedule and Notes .pdf below:

All lectures will be held at 4:00pm in the ENR2 building, Room S395 and on Zoom. Recordings of each lecture are posted below. We will use piazza for discussions of the lecture materials. If you are interested to contribute please sign up  piazza.com/arizona/spring2022/am101
This event is sponsored by the Department of Mathematics, the Program in Applied Mathematics GIDP, the Data Science Institute, the Department of Hydrology & Atmospheric Sciences, and the College of Science.
