What is … a Smoke Ring?

This page hosts information on Felix Knöppel's talk "What is … a Smoke Ring?" at the "What is …?" seminar. The talk will take place on Friday, October 19, 1pm at the BMS Loft at Urania. This talk will help you better understand the talk by Ulrich Pinkall, which will start at 2pm.

We will again be ordering delivery pizza. If you would like to order pizza with us, please arrive to the "What is …?" seminar by 12:45pm.

Abstract

This talk will give a short introduction to smoke rings and the rich theory to which they are connected. Smoke rings are closed curves that evolve by the vortex filament equation. This equation is connected to the non-linear cubic Schrödinger equation, which is well-known in the theory of solitons.
