The present paper introduces a very simple, but very useful notion of the so called quasi-extension of l 1 -operators and proves that a large class of topological vector spaces admit continuous hypercyclic operators. In particular, it answers in the affirmative a question of S. Rolewicz, posed in 19

✦ Synopsis
Two types of fundamental spaces of differential forms on infinite dimensional topological vector spaces are considered; one is a fundamental space of Hida's type and the other is one of Malliavin's. It is proven that the former space is smaller than the latter. Moreover, it is shown that, under some conditions, the fundamental space of Hida's type is nuclear as a complete countably normed space, while that of Malliavin's in the (L^{2}) sense is not.

The reduction of the Ѩ-problem on a Frechet nuclear space to the study of the Ѩ-operator on a Hilbert space produces a global solution u when the second member w factors globally through this Hilbert space. Easy counterexamples show that this global factorization is not in general possible and hence
An example of a Frechet space E is given such that the space of n-homogeneous ćontinuous polynomials on E, endowed with any of the natural topologies usually considered on it, is quasinormable for every n g N. This space has the particularity that all the natural topologies are different on it for n
## Abstract Generalized Orlicz–Lorentz sequence spaces __λ~φ~__ generated by Musielak‐Orlicz functions φ satisfying some growth and regularity conditions (see [28] and [33]) are investigated. A regularity condition __δ__^__λ__^ ~2~ for φ is defined in such a way that it guarantees many positive top
