Dancing Vortices – Étienne Ghys

University of Oxford Mathematical Institute

“Vortices do amazing things. They dance, they tie themselves in knots, they challenge mathematicians to explain them. In this case Étienne Ghys, CNRS Directeur de Recherche at the École Normale Supérieure de Lyon takes on the task of explaining.

“Oxford Mathematics was pleased to host this lecture as part of the Clay Mathematics Institute’s 2015 Research Conference.

“Étienne Ghys is the first recipient of the Clay Award for the Dissemination of Mathematical Knowledge.”
