Conjecture · version 1
Unforced global regularity on the three-torus
Statement
For every ν > 0 and every smooth divergence-free periodic initial velocity, the unforced incompressible Navier–Stokes equations admit global smooth periodic velocity and pressure on ℝ³/ℤ³.
Assumptions
- Three-dimensional unit-periodic domain.
- Positive viscosity and no external force.
Scope
The official alternative B; a separate domain from whole-space regularity.
