Description
I report on joint work with D. Cobb. We consider unique global in time solutions to the two dimensional Euler equations with initial data with sublinear growth and bounded vorticity. An easy check shows that the Leray projection to divergence free vector fields cannot be defined in this setting. Instead we construct unique solutions for which the velocity at x=0 vanishes for all times. This is possible by the Galilean invariance.
