Smooth global Lagrangian flow for the 2D Euler and second-grade fluid equations
We present a very simple proof of the global existence of a
Lagrangian flow map for the 2D Euler and second-grade fluid equations (on a
compact Riemannian manifold with boundary) which has dependence on
initial data in the class of divergence-free vector fields for
Global Well-Posedness of 2D Second Grade Fluid Equations in Exterior Domain
In this article, we consider 2D second grade fluid equations in exterior
domain with Dirichlet boundary conditions. For initial data , the system is shown to be global well-posed.
Furthermore, for arbitrary and , we prove that the solution
belongs to provided that
is in
