WebThe signed elementary product of I − AE corresponding to the permutation ρ is equal to Ce ρ − C o ρ . Proof. At the top-level, we proceed by induction on the number of cycles in the expression of ρ as a product of disjoint cycles. There are two base cases, followed by the inductive case. Base case 1: Identity permutation.
