Positive definite functions as uniformly ergodic multipliers of the Fourier algebra

Jorge Galindo, Enrique Jordá, Alberto Rodríguez-Arenas

Let G be a locally compact group and let $ϕ$ be a positive definite function on G with $ϕ (e) = 1$ . This function defines a multiplication operator $M_{ϕ}$ on the Fourier algebra $A (G)$ …

Generalized Hilbert operators acting on weighted spaces of holomorphic functions with sup-norms

María J. Beltrán-Meneu, José Bonet, Enrique Jordá

The behaviour of the generalized Hilbert operator associated with a positive finite Borel measure $μ$ on $[0, 1)$ is investigated when it acts on weighted Banach spaces of holomorph…

On the spectrum of isomorphisms defined on the space of smooth functions which are flat at 0

Enrique Jordá

In this note we study the spectrum and the Waelbroeck spectrum of the derivative operator composed with isomorphic multiplication oper

Dynamics of composition operators on function spaces defined by local and global properties

Angela A. Albanese, Enrique Jordá, Claudio Mele

In this paper we consider composition operators on locally convex spaces of functions defined on $R$ . We prove results concerning supercyclicity, power boundedness, mean e…

Inner derivations and weak-2-local derivations on the C $^{*}$ -algebra $C_{0} (L, A)$

E. Jordá, A. M. Peralta

Let $L$ be a locally compact Hausdorff space. Suppose $A$ is a C $^{*}$ -algebra with the property that every weak-2-local derivation on $A$ is a {\rm(}linear{\rm)} derivation. We prov…
