Spectral and ergodic properties of the operator $B (r, s)$ over power series spaces $Λ_{\infty} (α)$ of infinite type and their duals

Angela A. Albanese, Claudio Mele

In this paper, we investigate the spectral and ergodic properties of the linear operator $B (r, s)$ acting on power series spaces $Λ_{\infty} (α)$ of infinite type and on their strong d…

Mutual estimates of time-frequency representations and uncertainty principles

Angela A. Albanese, Claudio Mele, Alessandro Oliaro

In this paper we give different estimates between Lebesgue norms of quadratic time-frequency representations. We show that, in some cases, it is not possible to have such bounds in…

Multiplication and convolution topological algebras in spaces of $ω$ -ultradifferentiable functions of Beurling type

Angela A. Albanese, Claudio Mele

We determine multiplication and convolution topological algebras for classes of $ω$ -ultradifferentiable functions of Beurling type. Hypocontinuity and discontinuity of the multipli…

Spectra and ergodic properties of multiplication and convolution operators on the space $S (R)$

Angela A. Albanese, Claudio Mele

In this paper we investigate the spectra and the ergodic properties of the multiplication operators and the convolution operators acting on the Schwartz space $\mathcal{S}(\mathbb{…

Convolutors on $S_{ω} (R^{N})$

Angela A. Albanese, Claudio Mele

In this paper we continue the study of the spaces $O_{M, ω} (R^{N})$ and $O_{C, ω} (R^{N})$ undertaken in [1]. We determine new representations of suc…

Multipliers on $S_{ω} (R^{N})$

Angela A. Albanese, Claudio Mele

The aim of this paper is to introduce and to study the space $O_{M, ω} (R^{N})$ of the multipliers of the space $S_{ω} (R^{N})$ of the $ω$ -ultradiffere…
