Abstract:
In this paper we give a topology-dynamical interpretation for the space of all integer sequences P_n whose consecutive difference P_{n+۱}-P_n is a bounded sequence. We also introduce a new concept textit{"Rigid Banach space"}. A rigid Banach space is a Banach space X such that for every continuous linear injection j:Xto X,;overline{J(X)} is either isomorphic to X or it does not contain any isometric copy of X. We prove that ell_{infty} is not a rigid Banach space. We also discuss about rigidity of Banach algebras.
