SUMMARY:Seminar Analysis and Mathematical Physics: In-Jee Jeong (Seoul Nati
 onal University)
DESCRIPTION:The evolution of incompressible inviscid fluids is governed by 
 the Euler equations. We consider the dynamics of vortex rings\, which are 
 axisymmetric solutions to the three dimensional Euler equations with conce
 ntrated axial vorticity. We prove the following infinite norm growth resul
 ts: (i) filamentation (formation of a long tail) behavior from a single vo
 rtex ring\, and (ii) vortex stretching from the "collision" of two vortex 
 rings with opposite signs. Joint work with Kyudong Choi (UNIST).
