A characterization of the Schur property through the disk algebra

García, Domingo; Jorda Mora, Enrique; Maestre, Manuel (Elsevier, 2017-01-15)

[EN] In this paper we give a new characterization of when a Banach space E has the Schur property in terms of the disk algebra. We prove that E has the Schur property if and only if A(D, E) = A(D,E-w). (C) 2016 Elsevier ...
A teaching proposal for the study of Eigenvectors and Eigenvalues

Beltrán Meneu, María José; Murillo-Arcila, Marina; Jorda Mora, Enrique (Omnia Publisher SL, 2017)

[EN] In this work, we present a teaching proposal which emphasizes on visualization and physical applications in the study of eigenvectors and eigenvalues. These concepts are introduced using the notion of the moment of ...
Composition operators on the Schwartz space

GALBIS VERDU, ANTONIO; Jorda Mora, Enrique (European Mathematical Society Publishing House, 2018)

[EN] We study composition operators on the Schwartz space of rapidly decreasing functions. We prove that such a composition operator is never a compact operator and we obtain necessary or sufficient conditions for the range ...
Convergence of iterates of operators on Banach spaces

Zago, Nicola (Universitat Politècnica de València, 2023-09-22)

[ES] Consideramos el espacio L(X) de operadores acotados en un espacio de Banach X dotado de tres topologías localmente convexas naturales: la de la norma, la topología débil de operadores, y la topología fuerte de operadores. ...
Diseño e implementación de una estrategia de comunicación en redes sociales chinas de la actividad de grupos de investigación españoles

Luo, Weizhi (Universitat Politècnica de València, 2021-10-20)

[ES] Desde hace unas décadas, es natural que los investigadores colaboren con investigadores de otros países. Esto es incluso fomentado por los proyectos europeos de programas como H2020 o Eramus +. En la carrera de un ...
Dynamics and spectra of composition operators on the Schwartz space

FERNÁNDEZ ROSELL, CARMEN; GALBIS VERDU, ANTONIO; Jorda Mora, Enrique (Elsevier, 2018)

[EN] In this paper we study the dynamics of the composition operators defined in the Schwartz space of rapidly decreasing functions. We prove that such an operator is never supercyclic and, for monotonic symbols, it is ...
Dynamics of composition operators on function spaces defined by local and global properties

Albanese, Angela A.; Jorda Mora, Enrique; Mele, Claudio (Elsevier, 2022-10-01)

[EN] In this paper we consider composition operators on locally convex spaces of functions defined on R. We prove results concerning supercyclicity, power boundedness, mean ergodicity and convergence of the iterates in the ...
Dynamics of Weighted Composition Operators on Spaces of Entire Functions of Exponential and Infraexponential Type

Beltrán Meneu, María José; Jorda Mora, Enrique (Springer-Verlag, 2021-09-07)

[EN] Given an affine symbol phi and a multiplier w, we focus on the weighted composition operator C-w,C-phi acting on the spaces Exp and Exp(0) of entire functions of exponential and of infraexponential type, respectively. ...
Ergodic properties of composition operators on Banach spaces of analytic functions

Jorda Mora, Enrique; Rodríguez-Arenas, Alberto (Elsevier, 2020-06-01)

[EN] The composition operators defined on little Bloch spaces, Bergman spaces, Hardy spaces or little weighted Bergman spaces of infinite type, when well defined, are shown to be mean ergodic if and only if they are power ...
Ergodic properties of convolution operators

Galindo, Jorge; Jorda Mora, Enrique (Theta Foundation, 2021)

[EN] Let G be a locally compact group and µ be a measure on G. In this paper we find conditions for the convolution operators ¿p(µ) : L p (G) ¿ L p (G) to be mean ergodic and uniformly mean ergodic. The ergodic properties ...

[ES] El objetivo de esta tesis es estudiar las propiedades ergódicas (acotación en potencias, ergodicidad media y ergodicidad media uniforme) de operadores definidos en varios espacios de funciones. En un espacio Hausdorff ...
Extension operators for smooth functions on compact subsets of the reals

Frerick, Leonhard; Jorda Mora, Enrique; Wengenroth, Jochen (Springer-Verlag, 2020-08)

[EN] We introduce sufficient as well as necessary conditions for a compact set K such that there is a continuous linear extension operator from the space of restrictions C-infinity (K) = {F vertical bar(K) : F is an element ...
Inner Derivations and Weak-2-Local Derivations on the C*-Algebra C-0(L, A)

Jorda Mora, Enrique; Peralta, A.M. (Springer-Verlag, 2017-09)

[EN] Let L be a locally compact Hausdorff space. Suppose A is a -algebra with the property that every weak-2-local derivation on A is a (linear) derivation. We prove that every weak-2-local derivation on is a (linear) ...
