Stabilization in a chemotaxis system modelling T-cell dynamics with simultaneous production and consumption of signals

open access: yesEuropean Journal of Applied Mathematics
In a smoothly bounded domain $\Omega \subset \mathbb{R}^n$ , $n\ge 1$ , this manuscript considers the homogeneous Neumann boundary problem for the chemotaxis system \begin{eqnarray*} \left \{ \begin{array}{l} u_t = \Delta u - \nabla \cdot (

Weighted Estimates for Oscillatory Singular Integrals

open access: yesJournal of Function Spaces and Applications, 2013
We establish uniform bounds for oscillatory singular integrals as well as oscillatory singular integral operators. We allow the singular kernel to be given by a function in the Hardy space , while such results were known previously only for kernels in ...

Weighted variable Morrey–Herz estimates for fractional Hardy operators

open access: yesJournal of Inequalities and Applications, 2022
The present article discusses the boundedness criteria for the fractional Hardy operators on weighted variable exponent Morrey–Herz spaces M K ˙ q , p ( ⋅ ) α ( ⋅ ) , λ ( w ) ${M\dot{K}^{\alpha(\cdot),\lambda}_{q,p(\cdot)}(w)}$ .

Local Calderón-Zygmund estimates for parabolic equations in weighted Lebesgue spaces

open access: yesMathematics in Engineering, 2023
We prove local Calderón-Zygmund type estimates for the gradient of weak solutions to degenerate or singular parabolic equations of $ p $-Laplacian type with $ p > \frac{2n}{n+2} $ in weighted Lebesgue spaces $ L^q_w $.

Hertz potentials and asymptotic properties of massless fields

open access: yes, 2014
In this paper we analyze Hertz potentials for free massless spin-s fields on the Minkowski spacetime, with data in weighted Sobolev spaces. We prove existence and pointwise estimates for the Hertz potentials using a weighted estimate for the wave ...

Information estimators for weighted observations [PDF]

open access: yesNeural Networks, 2013
The Shannon information content is a valuable numerical characteristic of probability distributions. The problem of estimating the information content from an observed dataset is very important in the fields of statistics, information theory, and machine learning. The contribution of the present paper is in proposing information estimators, and showing

Comparisons of Methods of Estimation for a New Pareto-type Distribution

open access: yesStatistica, 2019
Bourguignon et al. (2016) introduced a new Pareto-type distribution to model income and reliability data. The aim of this paper is to estimate the parameters of this distribution from both frequentist and Bayesian view points.

Weighted and endpoint estimates for commutators of bilinear pseudo-differential operators

open access: yesAIMS Mathematics, 2022
In this paper, by applying the accurate estimates of the Hörmander class, the authors consider the commutators of bilinear pseudo-differential operators and the operation of multiplication by a Lipschitz function.

Weighted estimates for the multilinear maximal function

open access: yes, 2013
A formulation of the Carleson embedding theorem in the multilinear setting is proved which allows to obtain a multilinear analogue of Sawyer's two weight theorem for the multisublinear maximal function \mathcal{M} introduced in Lerner et al.
