Application of Bernstein polynomials to suppress the Gibbs effect (literature review)

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Background. Despite Gibbs effect (phenomenon) was discovered almost 170 years ago, the amount of works devoted to its research and the construction of methods of its suppression has not weakened until recently.

Detecting Relevant Deviations From the White Noise Assumption for Non‐Stationary Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of detecting deviations from a white noise assumption in time series. Our approach differs from the numerous methods proposed for this purpose with respect to two aspects. First, we allow for non‐stationary time series. Second, we address the problem that a white noise test is usually not performed because one believes ...

Empirical‐Process Limit Theory and Filter Approximation Bounds for Score‐Driven Time Series Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This article examines the filtering and approximation‐theoretic properties of score‐driven time series models. Under specific Lipschitz‐type and tail conditions, new results are derived, leading to maximal and deviation inequalities for the filtering approximation error using empirical process theory.

A Categorification of One-Variable Polynomials [PDF]

Discrete Mathematics & Theoretical Computer Science, 2015
We develop a diagrammatic categorification of the polynomial ring $\mathbb{Z} [x]$, based on a geometrically-defined graded algebra and show how to lift various operations on polynomials to the categorified setting.

P-Bernstein polynomials

Filomat
In this current study, we introduce a new operator called the P-Bernstein operator derived through the utilization of ?P-factorial? (Pell factorial) and ?Pellnomial? (Pell binomial). Subsequently, we investigate the fundamental properties of the P-Bernstein basis polynomials.

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Image encryption algorithm for crowd data based on a new hyperchaotic system and Bernstein polynomial

IET Image Processing, 2021
A new two‐dimensional chaotic system in the form of a cascade structure is designed, which is derived from the Chebyshev system and the infinite collapse system.

Evaluating Preclinical‐to‐Human Bioavailability Classification Using Smooth ROC Curve Estimation

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 5, May 2026.
ABSTRACT Human oral bioavailability is a critical pharmacokinetic parameter that determines systemic drug exposure, informs dose selection, and guides compound prioritization during early‐stage drug development. Although animal models are routinely employed to estimate human bioavailability, interspecies physiological differences and weak correlations ...

A NOTE ON THE GENERALIZED BERNSTEIN POLYNOMIALS

Honam Mathematical Journal, 2011
Summary: We prove two identities for multivariate Bernstein polynomials on simplices. In this paper, we study good approximations of Bernstein polynomials for every continuous function on simplices and the higher dimensional \(q\)-analogues of Bernstein polynomials on simplices.
