摘要:
We introduce the notion of an m-isometry of a Banach space, following a definition of Agler and Stankus in the Hilbert space setting. We give a first approach to the general theory of these maps. Then, we focus on the dynamics of m-isometries, showing that they are never N-supercyclic. This result is new even on a Hilbert space, and even for isometries on a general Banach space.
