Vortex Dynamics Research Group

Group seminars

Our group meets weekly (or so) on Wednesdays for an informal seminar or discussion group at 4 pm in the Mathematical Institute, Lecture Theatre B. All are welcome. It is also possible to participate in seminars via MS Teams. Please contact David Rees Jones for more information.
