The problem of regularity of solution (existence, uniqueness, and finite energy) of Navier Stokes equations is interesting for some mathematicians. It is well-known that calculations show a finite time blowup where the velocity diverges to infinity.
I tried to follow some books or articles to find out where the blowup emerges but, due to mathematical technicalities I couldn't track the calculations.
So my question basically is that if anyone can explain it in simpler manner? Or if anyone can suggest a reference that simply explains this blowup phenomenon.
Any comment and answer would be appreciated.
