Theorem · version 1
For an unforced three-dimensional Euler solution in the classical Sobolev class , , a finite maximal smooth lifespan T* requires . In particular, a finite value of this integral allows smooth continuation past that time.
Beale–Kato–Majda is a conditional criterion; it does not itself construct a singularity.
