Splitting and Merging of Stagnation Points of Solutions to the 2D Navier-Stokes Equations

Isidro Benaroya, Alberto Enciso, Daniel Peralta-Salas

We construct solutions to the Navier-Stokes equations on ${\mathbf{R}}^2$ with an arbitrary number of stagnation points which merge and split along trajectories that can be prescribe…
