Ferreira González, Chelo; López García, José Luis ; Pérez Sinusía, Ester (Springer, 2022)
Artículo / Artikulua
We obtain an asymptotic expansion of the hyperbolic umbilic catastrophe integral Ψ(H) (x,y,z) := ∫∞−∞∫∞−∞exp(i(s3+t3+zst +yt+xs))ds dt for large values of |x| and bounded values of |y| and |z|. The expansion is given ... -
Asymptotic expansions for Moench's integral transform of hydrology
López García, José Luis ; Pagola Martínez, Pedro Jesús ; Pérez Sinusía, Ester (MDPI, 2023)
Artículo / Artikulua
Theis' theory (1935), later improved by Hantush & Jacob (1955) and Moench (1971), is a technique designed to study the water level in aquifers. The key formula in this theory is a certain integral transform H[g](r,t) of ... -
Asymptotic greediness of the Haar system in the spaces Lp[0 , 1] , 1< p< ∞
Albiac Alesanco, Fernando José ; Ansorena, José L.; Berná, Pablo M. (Springer, 2019)
Artículo / Artikulua
Our aim in this paper is to attain a sharp asymptotic estimate for the greedy constant Cg[H(p), Lp] of the (normalized) Haar system H(p) in Lp[0 , 1] for 1 < p < ∞. We will show that the super-democracy constant of H(p) ... -
An axiomatic approach to finite means
Campión Arrastia, María Jesús ; Candeal, Juan Carlos; García Catalán, Olga Raquel ; Giarlotta, Alfio; Induráin Eraso, Esteban (Elsevier, 2018)
Artículo / Artikulua
In this paper we analyze the notion of a finite mean from an axiomatic point of view. We discuss several axiomatic alternatives, with the aim of establishing a universal definition reconciling all of them and exploring ... -
Bayesian inference in multivariate spatio-temporal areal models using INLA: analysis of gender-based violence in small areas
