On a 'philosophical' question about Banach envelopes
Albiac Alesanco, Fernando José ; Ansorena, José L.; Wojtaszczyk, Przemyslaw (Springer, 2021)
Artículo / Artikulua
We show how to construct non-locally convex quasi-Banach spaces X whose dual separates the points of a dense subspace of X but does not separate the points of X. Our examples connect with a question raised by Pietsch (Rev ... -

Artículo / Artikulua
In this paper we investigate the Meijer G-function G p+1,p+1 p,1 which, for certain parameter values, represents the Riemann-Liouville fractional integral of the Meijer-Nørlund function G p,p. p,0 The properties of this ... -

Artículo / Artikulua
The study of orders is a constantly evolving topic, not only for its interest from a theoretical point of view, but also for its possible applications. Recently, one of the hot lines of research has been the construction ... -
On admissible orders over closed subintervals of [0,1]
Santana, Fagner; Bedregal, Benjamin ; Viana, Petrucio; Bustince Sola, Humberto (Elsevier, 2020)
Artículo / Artikulua
In this paper, we make some considerations about admissible orders on the set of closed subintervals of the unit interval I[0,1], i.e. linear orders that refine the product order on intervals. We propose a new way to ... -
On certain subspaces of p for 0 < p ≤ 1 and their applications to conditional quasi-greedy bases in p-Banach spaces
Albiac Alesanco, Fernando José ; Ansorena, José L.; Wojtaszczyk, Przemyslaw (Springer, 2021)
Artículo / Artikulua
We construct for each 0<p≤1 an infinite collection of subspaces of ℓp that extend the example of Lindenstrauss (Bull. Acad. Polon. Sci. Sér. Sci. Math. Astronom. Phys. 12, 539–542, 1964) of a subspace of ℓ1 with no ... -
On co-orbital quasi-periodic motion in the three-body problem
Cors, Josep Maria; Palacián Subiela, Jesús Francisco ; Yanguas Sayas, Patricia (Society for Industrial and Applied Mathematics (SIAM), 2019)
Artículo / Artikulua
Within the framework of the planar three-body problem we establish the existence of quasi-periodic motions and KAM 4-tori related to the co-orbital motion of two small moons about a large planet where the moons move in ... -
On fixed point theory in partially ordered sets and an application to asymptotic complexity of algorithms
Estevan Muguerza, Asier ; Miñana, Juan José; Valero, Óscar (Springer, 2019)
Artículo / Artikulua
The celebrated Kleene fixed point theorem is crucial in the mathematical modelling of recursive specifications in Denotational Semantics. In this paper we discuss whether the hypothesis of the aforementioned result can be ... -
On fuzzy implications derived from general overlap functions and their relation to other classes
Pinheiro, Jocivania; Santos, Helida; Pereira Dimuro, Graçaliz; Bedregal, Benjamin ; Santiago, Regivan; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto (MDPI, 2023)
Artículo / Artikulua
There are distinct techniques to generate fuzzy implication functions. Despite most of them using the combination of associative aggregators and fuzzy negations, other connectives such as (general) overlap/grouping ... -
On some classes of directionally monotone functions
Bustince Sola, Humberto ; Mesiar, Radko; Kolesárová, Anna; Pereira Dimuro, Graçaliz ; Fernández Fernández, Francisco Javier ; Díaz, Irene; Montes Rodríguez, Susana (Elsevier, 2020)
Artículo / Artikulua
In this work we consider some classes of functions with relaxed monotonicity conditions generalizing some other given classes of fusion functions. In particular, directionally increasing aggregation functions (called also ... -
On some classes of nullnorms and h-pseudo homogeneity
Lima, Lucélia; Bedregal, Benjamin ; Rocha, Marcus; Castillo López, Aitor; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto (Elsevier, 2022)
Artículo / Artikulua
Nullnorms are aggregation functions which generalize t-norms and t-conorms. For each nullnorm there exists an annihilator element such that, below it, the function behaves like a t-conorm, and, above it, like a t-norm. ... -
On the nonlinear stability of the triangular points in the circular spatial restricted three-body problem
Cárcamo Díaz, Daniela Jacqueline; Palacián Subiela, Jesús Francisco ; Vidal Díaz, Claudio; Yanguas Sayas, Patricia (Pleiades Publishing, 2020)
Artículo / Artikulua
The well-known problem of the nonlinear stability of L4 and L5 in the circular spatial restricted three-body problem is revisited. Some new results in the light of the concept of Lie (formal) stability are presented. In ... -
On the norm-preservation of squares in real algebra representation
Albiac Alesanco, Fernando José ; Blasco, Óscar; Briem, E. (Springer, 2021)
Artículo / Artikulua
One of the main results of the article Gelfand theory for real Banach algebras, recently published in [Rev R Acad Cienc Exactas Fís Nat Ser A Mat RACSAM 114(4):163, 2020] is Proposition 4.1, which establishes that the norm ... -
On the normalization of interval data
Santiago, Regivan; Bergamaschi, Flaulles; Bustince Sola, Humberto ; Pereira Dimuro, Graçaliz ; Asmus, Tiago ; Sanz Delgado, José Antonio (MDPI, 2020)
Artículo / Artikulua
The impreciseness of numeric input data can be expressed by intervals. On the other hand, the normalization of numeric data is a usual process in many applications. How do we match the normalization with impreciseness on ... -
On the notion of fuzzy dispersion measure and its application to triangular fuzzy numbers
Roldán López de Hierro, Antonio Francisco; Bustince Sola, Humberto ; Rueda, María del Mar; Roldán, Concepción; Miguel Turullols, Laura de ; Guerra, Carlos (Elsevier, 2023)
Artículo / Artikulua
In this paper, based on the analysis of the most widely used dispersion measure in the real context (namely, the variance), we introduce the notion of fuzzy dispersion measure associated to a finite set of data given by ... -
On the performances of trend and change-point detection methods for remote sensing data
Militino, Ana F. ; Moradi, Mohammad Mehdi ; Ugarte Martínez, María Dolores (MDPI, 2020)

On the permutative equivalence of squares of unconditional bases
Albiac Alesanco, Fernando José ; Ansorena, José L. (Elsevier, 2022)
Artículo / Artikulua
We prove that if the squares of two unconditional bases are equivalent up to a permutation, then the bases themselves are permutatively equivalent. This settles a twenty-five year-old question raised by Casazza and Kalton ... -
