Part IIUnitary Even P

Abstract

Actual part iiunitary even p supplies the parameterized matrix, finite-field or ordered-product identities consumed by the whole-SU K5 width and intrinsic prescribed-product proof paths. All original hypotheses and actual carriers are retained; this source provides no oracle for bare automorphism recognition.

Definition 1.1 (p).

Lean statement: D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.p

Formalization. D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.p (✓ std3).

Source. Repository-derived.

Commentary.

Actual positive P element in the native anti-diagonal coordinates.

Theorem 1.2 (actual p entry).

Formalization. D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.Skew (✓ std3).

Source. Repository-derived.

Commentary.

The true P coordinate constraint, not an independently supplied unitary parameterization.

Theorem 1.7 (actual p unitary iff).

Lean statement: D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.actual_p_unitary_iff

Proof. Machine-checked in Lean as D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.actual_p_unitary_iff (✓ std3). ∎

Source. Repository-derived.

Commentary.

The parameterized actual p unitary iff statement describes the actual unitary geometry or prescribed ordered-product construction. Its Lean telescope retains every field, rank, involution, input and equality hypothesis shown.

Theorem 1.8 (actual even unitary U decomposition).

Lean statement: D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.actual_even_unitary_U_decomposition

Proof. Machine-checked in Lean as D5/S3/FiniteGroups/NikolovSegal/Unitary/PartIIUnitaryEvenP.actual_even_unitary_U_decomposition (✓ std3). ∎

Source. Repository-derived.

Commentary.

Actual even-dimensional p255 U=U2 P. The type-A block, P matrix, and skew-Hermitian law are constructed from the actual target.

The results concern special-unitary matrix groups over finite fields. Their geometric setting is Nikolov and Segal, On finitely generated profinite groups, II: Products in quasisimple groups, Annals of Mathematics 165 (2007), 239-273, DOI 10.4007/annals.2007.165.239. Prescribed-product statements retain their field-size, rank and automorphism hypotheses.
