摘要：
We study the time evolution of the support of a positive vorticity for a non-viscous incompressible fluid evolving in R(2) - D, where D is a compact domain with smooth boundary. We bound its growth. In the same time we prove also that a fluid particle initially close to the origin cannot go fast away.
