One of the 7 Clay Mathematics Institute $1 million Millennium Problems concerns existence and regularity of solutions to the Navier-Stokes equations. The problem was formulated in 2000 and I discussed certain very problematic aspects of the formulation in the following articles from 2008: On the Uniqueness of Weak Solutions of the Navier-Stokes Equations Is the Clay Navier-Stokes Problem Wellposed? also addressed […]

In short: Local implosion balanced by global explosion. Let us explore this natural and simple idea. Let us thus […]
