Titolo: On incompressible fluids with concentrated vorticity
Relatore: Professor Carlo MARCHIORO (U. Roma - La Sapienza)
 

Sommario

We consider an incompressible inviscid fluid moving into the whole

space. The initial data have one of these two symmetries: either a

planar one or an axisymmetry without swirl. We study a state with a

sharply concentrated vorticity and we prove that during a long time

evolution this large concentration remains. Few words are devoted to

the vanishing viscosity limit.
