I₃ eq

I₃_eq

Plain-language statement

A symmetry identity in the τ\tau-minimizer endgame. Let X1,X2X_1',X_2' be independent copies of X1,X2X_1,X_2, and set U=X1+X2U=X_1+X_2, V=X1+X2V=X_1'+X_2, W=X1+X1W=X_1'+X_1, and S=X1+X2+X1+X2S=X_1+X_2+X_1'+X_2'. Then the conditional mutual informations agree: I[V:WS]=I[U:WS]I[V:W\mid S]=I[U:W\mid S].

Inner eq inner conj of ker le

inner_eq_inner_conj_of_ker_le

Plain-language statement

Under the support condition σ.M.ker ≤ ρ.M.ker (i.e., supp(ρ) ⊆ supp(σ)), conjugation by σ^γ and σ^{-γ} preserves the inner product: ⟪ρ.M, H⟫ = ⟪σ^γ ρ σ^γ, σ^{-γ} H σ^{-γ}⟫. This holds because the kernel condition ensures ρ is supported on supp(σ), where σ^γ σ^{-γ} acts as the identity.
