Le Corp(u)s habité de Poussin

open access: yesPerspective, 2021
Nicolas Poussin’s Groupe de nymphes (Los Angeles, J. Paul Getty Museum) is sketch based on an ancient bas-relief of marine deities. On the verso of the drawing there is a fragmentary medical prescription for treatment of syphilis or morbus Gallicus.

The n-th prime asymptotically [PDF]

open access: yes, 2012
A new derivation of the classic asymptotic expansion of the n-th prime is presented. A fast algorithm for the computation of its terms is also given, which will be an improvement of that by Salvy (1994). Realistic bounds for the error with $\li^{-1}(n)$

Multivariate periodic wavelets of de la Vall\'ee Poussin type

open access: yes, 2014
In this paper we present a general approach to multivariate periodic wavelets generated by scaling functions of de la Vall\'ee Poussin type. These scaling functions and their corresponding wavelets are determined by their Fourier coefficients, which are ...

A formally verified proof of the prime number theorem

open access: yes, 2005
The prime number theorem, established by Hadamard and de la Vall'ee Poussin independently in 1896, asserts that the density of primes in the positive integers is asymptotic to 1 / ln x.

On the order of summability of the Fourier inversion formula [PDF]

open access: yes, 2010
In this article we show that the order of the point value, in the sense of Łojasiewicz, of a tempered distribution and the order of summability of the pointwise Fourier inversion formula are closely related.

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.

New moduli of smoothness

open access: yes, 2014
In this paper, we discuss various properties of the new modulus of smoothness \[ \omega^\varphi_{k,r}(f^{(r)},t)_p := \sup_{0 < h\leq t}\|\mathcal W^r_{kh}(\cdot) \Delta_{h\varphi(\cdot)}^k (f^{(r)},\cdot)\|_{L_p[-1,1]}, \] where $\mathcal W_\delta(x) = \

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
