Ultrametrics for context-aware comparison of binary images
López Molina, Carlos ; Iglesias Rey, Sara ; Baets, Bernard de (Elsevier, 2024)
Artículo / Artikulua
Quantitative image comparison has been a key topic in the image processing literature for the past 30 years. The reasons for it are diverse, and so is the range of applications in which measures of comparison are needed. ... -
Unconditional and quasi-greedy bases in L-p with applications to Jacobi polynomials Fourier series
Albiac Alesanco, Fernando José ; Ansorena, José L.; Ciaurri, Óscar; Varona, Juan L. (European Mathematical Society, 2019)
Artículo / Artikulua
We show that the decreasing rearrangement of the Fourier series with respect to the Jacobi polynomials for functions in L-p does not converge unless p = 2. As a by-product of our work on quasi-greedy bases in L-p(µ), we ... -
Unexpected thresholds from independence of irrelevant alternatives in fuzzy arrow theorems
Raventós Pujol, Armajac (2019)
Contribución a congreso / Biltzarrerako ekarpena
It is well known Arrow Theorem and its impact into Social Choice. It states that under an apparently mild set of conditions no rule fusing individual preferences into a social one is possible. In order to solve this ... -
A unified view of different axiomatic measures defined on L-fuzzy sets
Couso, Inés; Bustince Sola, Humberto ; Sánchez, Luciano (IEEE, 2019)
Artículo / Artikulua
The recent literature contains a multitude of extensions of (axiomatic) notions from the context of ordinary fuzzy sets to more general contexts. Using the language of lattices, we provide a general and compact formulation ... -
Uniform approximations of the first symmetric elliptic integral in terms of elementary functions

Artículo / Artikulua
We consider the standard symmetric elliptic integral RF(x, y, z) for complex x, y, z. We derive convergent expansions of RF(x, y, z) in terms of elementary functions that hold uniformly for one of the three variables x, y ... -
Uniform convergent expansions of integral transforms
López García, José Luis ; Palacios Herrero, Pablo ; Pagola Martínez, Pedro Jesús (American Mathematical Society, 2021)
Artículo / Artikulua
Several convergent expansions are available for most of the special functions of the mathematical physics, as well as some asymptotic expansions [NIST Handbook of Mathematical Functions, 2010]. Usually, both type of ... -
Uniform convergent expansions of the error function in terms of elementary functions
Ferreira González, Chelo; López García, José Luis ; Pérez Sinusía, Ester (Springer, 2023)
Artículo / Artikulua
We derive a new analytic representation of the error function erfz in the form of a convergent series whose terms are exponential and rational functions. The expansion holds uniformly in z in the double sector | arg (±z) ... -
Uniformly convergent expansions for the generalized hypergeometric functions p –1Fp and pFp
López García, José Luis ; Pagola Martínez, Pedro Jesús ; Karp, D. B. (Taylor & Francis, 2020)
Artículo / Artikulua
We derive a convergent expansion of the generalized hypergeometric function p−1 F p in terms of the Bessel functions 0 F 1 that holds uniformly with respect to the argument in any horizontal strip of the complex plane. We ... -
A uniformly convergent scheme to solve two-dimensional parabolic singularly perturbed systems of reaction-diffusion type with multiple diffusion parameters
Clavero, Carmelo; Jorge Ulecia, Juan Carlos (John Wiley & Sons Ltd, 2021)
Artículo / Artikulua
In this work, we deal with solving two-dimensional parabolic singularly perturbed systems of reaction-diffusion type where the diffusion parameters at each equation of the system can be small and of different scale. In ... -
