Abstract
We give an elementary proof of the well-known fact that shift-invariant operators onL 2[0, ∞) are represented by transfer functions which are bounded and analytic on the right open half-plane. We prove a generalization to Banach space-valuedL p-functions, where 1≤p<∞. We show that the result no longer holds forp=∞.
