The major point here is that, for an operator S on a Banach space (or Hilbert space) X, the number sup x ∈ X ∖ { 0 } ‖ S x ‖ ‖ x ‖ is not the spectral radius of S but the operator norm. The operator norm is always ≥ the spectral radius, but we cannot expect equality in general. On a Hilbert space, one sufficient ...
