A semi-implicit fully exactly well-balanced relaxation scheme for the shallow water system.
Caballero Cárdenas, Celia; Castro-Díaz, Manuel Jesús
; Chalons, Christophe; Morales-de-Luna, Tomás; Muñoz-Ruiz, María de la Luz (SIAM, 2024)
This article focuses on the design of semi-implicit schemes that are fully well-balanced for the one-dimensional shallow water equations, that is, schemes that preserve all smooth steady states of the system and not just ... -
Generalized convolution quadrature for non smooth sectorial problems
Guo, J.; López-Fernández, María (Springer, 2024)
We consider the application of the generalized convolution quadrature (gCQ) to approximate the solution of an important class of sectorial problems. The gCQ is a generalization of Lubich’s convolution quadrature (CQ) that ... -

Weak and Strong Type Estimates for the Multilinear Littlewood–Paley Operators.
(Springer Nature, 2021)Let be the multilinear square function defined on the cone with aperture . In this paper, we investigate several kinds of weighted norm inequalities for . We first obtain a sharp weighted estimate in terms of aperture ... -
On two weight estimates for iterated commutators.
(Elsevier, 2021)In this paper we extend the bump conjecture and a particular case of the separated bump conjecture with logarithmic bumps to iterated commutators . Our results are new even for the first order commutator . A new bump ... -
Quantitative matrix weighted estimates for certain singular integral operators.
(Elsevier, 2021)In this paper quantitative weighted matrix estimates for vector valued extensions of -Hörmander operators and rough singular integrals are studied. Strong type estimates, endpoint estimates, and some new results on ... -
Weighted Lp estimates on the infinite rooted k-ary tree.
(Springer Nature, 2021)In this paper sufficient conditions for weighted weak and strong type (p, p) estimates with for the centered maximal function on the infinite rooted k-ary tree are provided. Here the line initated by the authors and ... -
Upper endpoint estimates and extrapolation for commutators.
(Instituto de Matemática de Bahía Blanca (CONICET - UNS), 2023)In this note we revisit the upper endpoint estimates for commutators following the line by Harboure, Segovia, and Torrea [Illinois J. Math. 41 no. 4 (1997), 676–700]. Relying upon the suitable BMO subspace suited for the ... -
A class of multilinear bounded oscillation operators on measure spaces and applications.
(Springer Nature, 2023)recent years, dyadic analysis has attracted a lot of attention due to the conjecture. It has been well understood that in the Euclidean setting, Calderón–Zygmund operators can be pointwise controlled by a finite number ... -
On the sharpness of some quantitative Muckenhoupt-Wheeden inequalities.
(Académie des sciences, 2024). In the recent work [Cruz-Uribe et al. (2021)] it was obtained that |{x ∈ R d : w(x)|G(f w−1 )(x)| > α}| ≲ [w] 2 A1 α Z Rd |f |dx both in the matrix and scalar settings, where G is either the Hardy–Littlewood ... -
Endpoint Entropy Fefferman–Stein Bounds for Commutators.
(Springer Nature, 2023)In this paper endpoint entropy Fefferman–Stein bounds for Calderón–Zygmund operators introduced by Rahm (J Math Anal Appl 504(1):Paper No. 125372, 2021) are extended to iterated Coifman–Rochberg–Weiss commutators. -
Sharp A1 weighted estimates for vector valued operators.
(Springer Nature, 2021)Given 1 ≤ q < p < ∞, quantitative weighted L p estimates, in terms of Aq weights, for vector-valued maximal functions, Calderón–Zygmund operators, commutators, and maximal rough singular integrals are obtained. The results ... -

A sparse approach to mixed weak type inequalities.
(Springer Nature, 2019-12-10)Abstract. In this paper we provide some quantitative mixed weak-type estimates assuming conditions that imply that uv ∈ A∞ for Calder´on-Zygmund operators, rough singular integrals and commutators. The main novelty of ... -
Statistical properties of partially observed integrated functional depths
(Springer, 2024)Integrated functional depths (IFDs) present a versatile toolbox of methods introducing notions of ordering, quantiles, and rankings into a functional data analysis context. They provide fundamental tools for nonparametric ... -
