LeanPool.NavierStokesAndEuler.Euler.GevreyRestriction

Exact restriction compatibility of actual finite Gevrey energies and derivative losses.

theorem EulerGevreyRestriction.weightedNorm_restrict (period : ) [Fact (0 < period)] {p q : } (hqp : q p) (r N : ) (hN : N + r q) (ρ : ) (u : (EulerCylinderSobolevSpace.SobolevSpace period p)) :

Actual Gevrey norms are identical under every restriction retaining their derivative cutoff.

theorem EulerGevreyRestriction.weightedLoss_restrict (period : ) [Fact (0 < period)] {p q : } (hqp : q p) (r N : ) (hN : N + r q) (ρ : ) (u : (EulerCylinderSobolevSpace.SobolevSpace period p)) :

The actual radius-loss sum is identical under every restriction retaining its cutoff.

theorem EulerGevreyRestriction.wordAtLevel_restrict (period : ) [Fact (0 < period)] {p q r n : } (hqp : q p) (w : Fin nFin 4) (hq : n + r q) (u : (EulerCylinderSobolevSpace.SobolevSpace period p)) :

Actual derivative words agree after restricting the input to any sufficiently high Sobolev level.

theorem EulerGevreyRestriction.energyValues_restrict (period : ) [Fact (0 < period)] {p q : } (hqp : q p) (r N : ) (hN : N + r q) (u : (EulerCylinderSobolevSpace.SobolevSpace period p)) :

Every literal metric-energy derivative is unchanged by a valid Sobolev restriction.

The complete-solution truncation leaves every retained actual Gevrey norm unchanged.

The complete-solution truncation leaves the retained radius-loss sum unchanged.
