I am wondering if anyone has ever come up with a mathematical description of something that (to me, and I am no expert) look like soliton vortexes.
The example I can think of is if you create two vortexes, one spinning clockwise, and the other anticlockwise, on the surface of water. In the following video, this is done using a ceramic plate: http://www.youtube.com/watch?v=pnbJEg9r1o8. You immerse the plate in the water, perpendicular to the surface of the water, and move the plate in a direction perpendicular to its surface, and finally extract the plate.
Can questions such as: is this a soliton? Does it exist? What is the time of existence? etc... be answered from the Euler / Navier Stokes Equations? Quick look on the arXiv made me a little confused.
Any help or reference will be appreciated.
