WebLet v be an eigenvector corresponding to an eigenvalue λ: A T A v = λ v. We note that for any vector y, ‖ y ‖ 2 2 = y T y. We apply x T to the above equation: v T A T A v = λ v T v ⇔ ‖ A v ‖ 2 2 = λ ‖ x ‖ 2. This implies that λ ≥ 0. So ρ ( A T A) = max i λ i. Going back to the definition of the norm.
