✦ Synopsis
We are concerned with the following question: when can a polynomial P:
Ž . E ª X E and X are Banach spaces be extended to a Banach space containing E? We prove that the polynomials that are extendible to any larger space are Ž X . precisely those which can be extended to C B , if X is complemented in its E Ž X . bidual, and l B in general. We also show that the extendibility is a property that ϱ E is preserved by Aron᎐Berner extensions and composition with linear operators. We construct a predual of the space of extendible polynomials for the case that X is a dual space.

## Abstract This article deals with the relationship between an operator ideal and its natural polynomial extensions. We define the concept of coherent sequence of polynomial ideals and also the notion of compatibility between polynomial and operator ideals. We study the stability of these properti
Some applications of Ramsey theory to the study of multilinear forms and polynomials on Banach spaces are given, related to the existence of lower l -estiq mates of sequences. We give an explicit representation of subsymmetric polynomials in Banach spaces with subsymmetric basis. Finally we apply ou
Let F be a Banach or a nuclear Frechet space isomorphic to its square. Then Ž2 . P F , the space of 2-homogeneous polynomials on F, is isomorphic to the space Ž . of continuous linear operators L F, FЈ , both of them endowed with the topology of uniform convergence on bounded sets. In this note we p
## Abstract 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__‐s
