A dynamical characterization of sub-Arakelian subsets [Article]
(Elsevier, 2013-09-15)We are going to characterize those sets which can be covered by an Arakelian set in terms of dynamical properties of entire functions via similarities. Moreover, if we consider the set of universal entire functions via ...

Algebraic structure of continuous, unbounded and integrable functions [Article]
(Elsevier, 2019-02)In this paper we study the large linear and algebraic size of the family of unbounded continuous and integrable functions in [0, +∞) and of the family of sequences of these functions converging to zero uniformly on ...

Aproximación en variable compleja [Final Degree Work]
(2016-09)In the late Nineteenth Century, Weierstrass showed that any continuous real function in a compact can be uniformly approximated by polynomials, but this theorem is not valid for complex functions. In this context, Runge ...

Cyclicity of coefficient multipliers: Linear structure [Article]
(Springer, 2007-03)In this paper we characterize various kinds of cyclicity of sequences of coefficient multipliers, which are operators defined on spaces of holomorphic functions. In the case of a single coefficient multiplier we characterize ...

Hausdorff and Box dimensions of continuous functions and lineability [Article]
(Taylor & Francis, 2019-05)Given s ∈ (1, 2], we study (among other questions) the algebraic genericity of the set of continuous functions f : [0, 1] → R whose graph has Hausdorff (or Box) dimension exactly s.

Holomorphic operators generating dense images [Article]
(Springer, 2008-01)The existence of infinite dimensional closed linear spaces of holomorphic functions f on a domain G in the complex plane such that T f has dense images on certain subsets of G, where T is a continuous linear operator, is ...

Large subspaces of compositionally universal functions with maximal cluster sets [Article]
(Elsevier, 2012-02)Let (φn) be a sequence of holomorphic self-maps of a Jordan domain G in the complex plane. Under appropriate conditions on (φn), we construct an H(G)-dense linear manifold –as well as a closed infinite-dimensional ...

Lineabilidad en espacios de sucesiones [Master's Thesis]
(2016-06)Desde siempre, grandes matemáticos de todas las épocas se han sentido atraídos y fascinados por la existencia de grandes estructuras algebraicas que verifican ciertas propiedades que, a priori, contradicen la intuición ...

Lineabilidad y curvas de Peano [Master's Thesis]
(2018)Las curvas de Peano pueden generalizarse y entenderse: o bien como aplicaciones continuas y sobreyectivas entre dos espacios X e Y , o bien como curvas cuya imagen tiene área. Cada una de estas dos interpretaciones define ...

Lineability and modes of convergence [Article]
(Springer, 2020-01)In this paper we look for the existence of large linear and algebraic structures of sequences of measurable functions with different modes of convergence. Concretely, the algebraic size of the family of sequences that are ...

Lineability in sequence and function spaces [Article]
(Polish Academy of Sciences, Institute of Mathematics, 2017)It is proved the existence of large algebraic structures –including large vector subspaces or infinitely generated free algebras– inside, among others, the family of Lebesgue measurable functions that are surjective in a ...

Matemáticas: una ¿triste? historia de amor [Article]
(2014-12-25)Recientemente me encontré en Twitter el vídeo Math tell us three of the saddest love stories del blog Lemongum sobre cómo las matemáticas nos cuentan las historias de amor más tristes. En el presente artículo vamos a ...

Maximal cluster sets along arbitrary curves [Article]
(Elsevier, 2004-08)The existence of a dense linear manifold of holomorphic functions on a Jordan domain having except for zero maximal cluster set along any curve tending to the boundary with nontotal oscillation value set is shown.

Maximal cluster sets of L-analytic functions along arbitrary curves [Article]
(Springer, 2007-03)Let Ω be a domain in the N-dimensional real space, L be an elliptic differential operator, and (Tn) be a sequence whose members belong to a certain class of operators defined on the space of L-analytic functions on Ω. ...

Maximal cluster sets on spaces of holomorphic functions [Article]
(Oldenbourg, 2004)This is an expository paper where we relate some aspects of the problem of looking for holomorphic functions with maximal cluster sets under the action of operators defined on spaces of holomorphic functions. Some functional ...

Simultaneously maximal radial cluster sets [Article]
(Elsevier, 2005-07)In this paper, we show that for a wide class of operators T –including infi- nite order differential operators, and multiplication and composition operators– acting on the space H(D) of holomorphic functions in the unit ...

Subspaces of frequently hypercyclic functions for sequences of composition operators. [Article]
(Springer, 2019-02)In this paper, a criterion for a sequence of composition operators defined on the space of holomorphic functions in a complex domain to be frequently hypercyclic is provided. Such a criterion improves some already known ...
