Compatible Versus Regular Well-Posed Linear Systems

We discuss different regularity notions for Lp-wellposed linear systems with 1 p < ∞: – compatibility in the sense of Helton (1976), – weak regularity in the sense of Weiss and Weiss (1997) or Staffans and Weiss (2000), – strong regularity in the sense of Weiss (1994a), – uniform regularity in the sense of Helton (1976) and Ober and Wu (1996).
