1. This meeting fulfils two functions: It is the first Workshop of a six-month Newton Institute programme on Topological Dynamics in the Physical and Biological Sciences. It is an IUTAM Symposium, a sequel to The IUTAM Symposium Topological Fluid Mechanics held in Cambridge, August 1989

3. The 1989 Symposium focused on: Flow kinematics and Lagrangian chaos; Dynamo theory; Relaxation and formation of discontinuities; Two-dimensional and quasi-two-dimensional flows; Topology of three-dimensional flows; Vortex interaction and reconnexion; Homogeneous turbulence; Inhomogeneous turbulence and convective flows. The 2012 Symposium has been planned to focus mainly on: Steady vortical solutions of the Euler equations and their stability; Interaction of vortex pairs, vortex rings, etc Vortex reconnection by viscosity; The finite-time singularity problem for Euler and Navier-Stokes; Application to the structure of turbulence and the process of turbulent dissipation....but flow kinematics and Lagrangian chaos remains a hot topic, and so is also included.

5. Proceedings of this Symposium IUTAM has a contract with Elsevier for online publication of its Symposia Proceedings in their series “IUTAM Procedia”; open source, so freely available. We have driven a ‘hard bargain’ with Elsevier for the Procedia of this Symposium. It will be possible to order hard copies of the volume at a price of c. $40 per volume (paperback). We hope you will submit your paper soon (if you have not already done so). If you are giving a lecture, a LaTex template has been sent to you. If you have any problem with this, please let us know, and we will try to sort it out. Your contribution will be reviewed, and a decision on acceptance sent to you by 15 September; Deadline for receipt of revised version: 31 October

6. Hassan Aref Virginia Tech. 28 Sept. 1950 – 9 Sept. 2011 I wish to pay tribute to Hassan Aref, who was a member of the International Scientific Committee of this IUTAM Symposium. He was a distinguished member of the IUTAM community, and Secretary of the Congress Committee of IUTAM, a position of great responsibility. He died suddenly of heart failure on 9th September 2011. Mark Stremler has taken Hassan’s place on the Committee of this Symposium. Morten Brøns will give the Aref Memorial Lecture tomorrow (Tuesday, 16:45-17:30) Relative equilibria of point vortices.
