Weak solutions, renormalized solutions and enstrophy defects in 2D turbulence
Milton C. Lopes Filho, Anna L. Mazzucato, Helena J. Nussenzveig Lopes
Enstrophy, half the integral of the square of vorticity, plays a role in 2D turbulence theory analogous to that played by kinetic energy in the Kolmogorov theory of 3D turbulence.…

Two dimensional incompressible ideal flow around a small obstacle
D. Iftimie, M. C. Lopes Filho, H. J. Nussenzveig Lopes
In this article we study the asymptotic behavior of incompressible, ideal, time-dependent two dimensional flow in the exterior of a single smooth obstacle when the size of the obst…
