Before anyone says, "This is just the Ladyzhenskaya model" or "Smagorinsky closure":
Mathematically? Yes, it's in the same class.
But the distinction matters: Ladyzhenskaya added a term to fix the math. I'm arguing that kinetic theory and geometric constraints require this term to exist.
The standard constant-viscosity model isn't the "pure" truth; it's a low-strain approximation that fails at the extremes.
You're fighting mathlib because you're trying to prove regularity for a model that likely doesn't have it.
The standard constant-viscosity equation allows energy concentration that standard analytic bounds can't control. The issue isn't Lean; it's that the physics is degenerate at the singularity.
If you add geometric feedback (strain-dependent viscosity), the 'Regularity Gap' closes immediately. 👇
@cobyymj Disgusted that as a female streamer you chose to call this woman out for setting boundaries in a male dominated space where 99% of her interactions are with creepy, entitled men trying to score a free orgasm. Normalizing this kind of harassment on a streamers own channel is gross
