The geometric analysis of geodesic flow on the group of volume-preserving diffeomorphisms, SDiff, answers fundamental questions about the motion of an ideal fluid, such as questions of existence and stability of the solutions to the Euler equations. Recently, great progress has been made in a number of directions: it has been proven that any two fluid configurations can be connected by a generalized flow, the exponential map on SDiff(Tn) has been show to be Fredholm, and new averaged Euler equations have been obtained as geodesics on SDiff with H1 (as opposed to L2) metric. This symposium will explore the connections between these new developments and their consequences for a better understanding of fluid motion.
