Smooth partitions of unity on some non-separable Banach spaces
Snakes and articulated arms in an Hilbert space
The purpose of this paper is to give an illustration of results on integrability of distributions and orbits of vector fields on Banach manifolds obtained in [5] and [4]. Using arguments and results of these papers, in the context of a separable Hilbert space, we give a generalization of a Theorem of accessibility contained in [3] and [6] for articulated arms and snakes in a finite dimensional Hilbert space.
Sur les endomorphismes polynomiaux permutables de
Dans cet article, nous déterminons tous les couples d’endomorphismes polynomiaux permutables de degrés supérieurs à 1 de qui se prolongent en des endomorphismes holomorphes de et qui possèdent deux suites d’itérés disjointes.
