A Note on Some Strongly Sequence Spaces

open access: yesAbstract and Applied Analysis, 2011
We introduce and study new sequence spaces which arise from the notions of generalized de la Vallée-Poussin means, invariant means, and modulus functions.

Poussin à la rencontre du Tasse

open access: yesCahiers d’Études Romanes, 2005
Sous l’effet d’une passion très tôt revendiquée et jamais démentie pour le Tasse et pour sa grande épopée chrétienne, Nicolas Poussin a illustré, dans chaque cas à deux reprises, les émois amoureux de Renaud et d’Armide, et ceux de Tancrède et d’Herminie.

The Very Idea of Seriousness

open access: yesEuropean Journal of Philosophy, EarlyView.
Abstract What norms govern aesthetic conversations? In Hansen and Adams (2024), we argue for a norm we call, following Stanley Cavell, “the hope of agreement”, along with a requirement of “seriousness”, the “discipline of accounting for one's judgments”.

APPROXIMATION BY LINEAR MEANS OF FOURIER SERIES AND REALIZATION FUNCTIONALS IN WEIGHTED ORLICZ SPACES

open access: yesПроблемы анализа, 2022
Using one-sided Steklov means, we introduce a new modulus of smoothness in weighted Orlicz spaces and state its equivalence with a special 𝐾-functional. We prove Stechkin-Nikol’skii-type inequality for trigonometric polynomials and direct estimates for

Tensor Changepoint Detection and Eigenbootstrap

open access: yesJournal of Time Series Analysis, Volume 47, Issue 3, Page 557-578, May 2026.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

Between Coloris and Dessein

open access: yesBulletin du Centre de Recherche du Château de Versailles, 2006
Charles de La Fosse is associated with two defining, if opposed, poles of Academic theory and practice: the dessein camp associated with the practice and theory of Charles Le Brun; and the coloris camp, associated with the theory of Roger de Piles and ...

Negativity of Green’s Functions to Focal and Two-Point Boundary Value Problems for Equations of Second Order with Delay and Impulses in Their Derivatives

open access: yesMathematics, 2022
We consider the second-order impulsive differential equation with impulses in derivative and without the damping term. Sufficient conditions that a nontrivial solution of the homogeneous equation having a zero of its derivative does not have a zero ...

Locally Bounded Second κ‐Variation Solution of an Integro‐Differential Equation With Infinite Delay

open access: yesInternational Journal of Differential Equations, Volume 2026, Issue 1, 2026.
This work presents conditions under which the Volterra integral equation of the second kind admits a unique solution in the class of locally bounded second κ‐variation functions on [0, +∞). Our approach relies on successive Picard iterations to obtain such a solution on a compact interval, and then to prolong it to [0, +∞).

De la Vallée Poussin problem in the kernel of the convolution operator on the half-plane

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
We consider the multipoint de la Vallée Poussin (interpolational) problem in the half-plane $D$, $D=\{z \, :\, \mathop{\mathrm{Re}} z0\}$. Let $\psi(z)\in H(D)$; $\mu_1$, $\mu_2$,~$\ldots \in D$ be the positive zero points of this function and let the ...
