Convergence in the Cesàro sense of ergodic operators associated with a flow.
(2000)We study the a.e. convergence ofthe Ceshro-(1 +c) ergodic averages and the a.e. existence in the Ceso-u sense ofthe ergodic Hilbert transform associated with a Cesobounded flow and < c < 0. -
Two-weight norm inequalities for the fractional maximal operator on spaces of homogeneous type
(Institute of Mathematics, Polish Academy of Sciences, 1994) -
Fractional derivative description of the bloch space
(Springer Nature, 2024-01-09)We establish new characterizations of the Bloch space B which include descriptions in terms of classical fractional derivatives. Being precise, for an analytic function f (z) = E∞n=0 ^f(n)zn in the unit disc D, we define ... -
Bergman projection on Lebesgue space Induced by doubling weight
(Springer Nature, 2023-11-28)Let ω and ν be radial weights on the unit disc of the complex plane, and denote σ = ωp′ ν− p′ p and ωx = ∫ 1 0 sxω(s) ds for all 1 ≤ x < ∞. Consider the one-weight inequality ‖Pω (f )‖Lp ν ≤ C‖f ‖Lp ν , 1 < p < ∞, ... -
Mixed weak-type inequalities in Euclidean spaces and in spaces of the homogeneous type
(Wiley, 2023-11-05)In this paper, we provide mixed weak-type inequalities generalizing previous results in an earlier work by Caldarelli and the second author and also in the spirit of earlier results by Lorente et al. One of the main novelties ... -
A Bayesian approach to the multivariate Behrens-Fisher problem.
(2023)The multivariate Behrens-Fisher problem consists of testing the equality of the mean vectors of two independent multivariate normal populations with unknown and arbitrary covariance matrices. In this work we provide a ... -
Tight and Compact Sample Average Approximation for Joint Chance-Constrained Problems with Applications to Optimal Power Flow.
(INFORMS, 2023-08-02)In this paper, we tackle the resolution of chance-constrained problems reformulated via sample average approximation. The resulting data-driven deterministic reformulation takes the form of a large-scale mixed-integer ... -
Hilbert-type operator induced by radial weight on Hardyspaces
(Springer Nature, 2023-09-19)We consider the Hilbert-type operator defined by Hω(f)(z)=∫10f(t)(1z∫z0Bωt(u)du)ω(t)dt, where {Bωζ}ζ∈D are the reproducing kernels of the Bergman space A2ω induced by a radial weight ω in the unit disc D. We prove ... -
High-order fully well-balanced numerical methods for one-dimensional blood flow with discontinuous properties
(Elsevier, 2022-12-27)In this paper, we are interested in the numerical study of the one-dimensional blood flow model with discontinuous mechanical and geometrical properties. We present the mathematical model together with its nondimensional ... -
Some quantitative one-sided weighted estimates
(Elsevier, 2022-12-20)We show a link between affine differential geometry and null submanifolds in a semi-Riemannian manifold via statistical structures. Once a rigging for a null submanifold is fixed, we can construct a semi-Riemannian metric ... -
Implicit and implicit-explicit Lagrange-projection finite volume schemes exactly well-balanced for 1D shallow water system
(Elsevier, 2022-12-25)In this paper we consider the Lagrange-Projection technique in the framework of finite volume schemes applied to the shallow water system. We shall consider two versions of the scheme for the Lagrangian step: one fully ... -
One-sided Cp estimates via M# function.
(Cambridge, 2022-07-04)We recall that w ∈ C+p if there exist " > 0 and C > 0 such that for any a < b < c with c − b < b − a and any measurable set E ⊂ (a, b), the following holds. This condition was introduced by Riveros and de la Torre as a ... -
Operators induced by radial measures acting on the Dirichlet space
(Springer, 2023)Let D be the unit disc in the complex plane. Given a positive finite Borel measure μ on the radius [0, 1), we let μn denote the n-th moment of μ and we deal with the action on spaces of analytic functions in D of the ... -
Orbital debris and the market for satellites
(Elsevier, 2023)This paper studies the economic consequences of orbital debris for commercial outer-space activities. Spacecraft launches and other outer-space human activities produce pollution (i.e., orbital debris), which represent a ... -
Cesàro-type operators associated with Borel measures on the unit disc acting on some Hilbert spaces of analytic functions
(Elsevier, 2023)Given a complex Borel measure μon the unit disc D={z∈C:|z| <1}, we consider the Cesàro-type operator Cμdefined on the space Hol(D)of all analytic functions in Das follows: If f∈Hol(D), f(z) = ∞n=0anzn(z∈D), then Cμ(f)(z) ... -
Weighted weak-type iterated and bilinear Hardy inequalities
(Elsevier, 2023)We characterize the good weights for a certain weighted weak-type iterated Hardy inequality to hold. As a consequence, we get the characterizations of some weighted weak-type bilinear Hardy inequalities. -
Implicit and semi-implicit well-balanced finite-volume methods for systems of balance laws
(Elsevier, 2022-09-30)The aim of this work is to design implicit and semi-implicit high-order well-balanced finite-volume numerical methods for 1D systems of balance laws. The strategy introduced by two of the authors in some previous papers ...
