Abstract
For the 2-dimensional Navier–Stokes System written for the stream functions we construct a set of initial data for which initial critical points bifurcate into three critical points. This can be interpreted as the birth of new viscous vortices from a single one. In another class of solutions vortices merge, i.e. the number of critical points decrease.

Notes

Strictly speaking, we should consider the Galerkin approximations of our system to avoid issues connected with the infinite dimensionality of our system.
