Intrinsic ideal increments of the three actual probe sheets
- theorem
OAI.PolycyclicRecognition.intrinsic_probe_inverse_flowline 16Source documentation
The intrinsic inverse flow is precisely conjugation back by the normalized neighbor step.
theorem intrinsic_probe_inverse_flow (ι : I →* N) (φ : MulAut I) (k : N) (hφ : ∀ z, ι (φ z) = k * ι z * k⁻¹) (i : I) : k⁻¹ * ι i * k = ι (φ.symm i) := by … - theorem
OAI.PolycyclicRecognition.intrinsic_probe_tile_memline 26Source documentation
The tile covering gives an actual small ideal coordinate, without choosing a second preimage of a point under the ambient inclusion.
theorem intrinsic_probe_tile_mem (φ : MulAut I) (a i : I) (B : Set I) (hi : i ∈ a • (φ '' B)) : φ.symm (a⁻¹ * i) ∈ B := by … - theorem
OAI.PolycyclicRecognition.coneProbe_intrinsic_anchor_incrementline 35Source documentation
The anchor chain starts at the second original sheet and uses the reverse-flow anchor controlled by the larger template.
theorem coneProbe_intrinsic_anchor_increment (ι : I →* N) (φ : MulAut I) (k : N) (hφ : ∀ z, ι (φ z) = k * ι z * k⁻¹) (S : MulAut N) (n : N) (a : I) : (n * S k)⁻¹ * coneProbeSecond S n (ι a) k = S (ι (φ.symm a)) := by … - theorem
OAI.PolycyclicRecognition.coneProbe_intrinsic_tile_incrementline 44Source documentation
The within-tile chain has the intrinsic ideal coordinate supplied by that same tile; it keeps the actual endpoint being counted.
theorem coneProbe_intrinsic_tile_increment (ι : I →* N) (φ : MulAut I) (k : N) (hφ : ∀ z, ι (φ z) = k * ι z * k⁻¹) (S : MulAut N) (n : N) (a i : I) : (coneProbeSecond S n (ι a) k)⁻¹ * coneProbeSecond S n (ι i) k = S (ι (φ.symm (a⁻¹ * i))) := by …
