Quantifying non-monotonicity of functions and the lack of positivity in signed measures
Modern Stochastics: Theory and Applications, 2017 In various research areas related to decision making, problems and their solutions frequently rely on certain functions being monotonic. In the case of non-monotonic functions, one would then wish to quantify their lack of monotonicity.

A Comparison of Papoulis and Chebyshev Filters in the Continuous Time Domain [PDF]
Radioengineering, 2021 The subject of this paper is the revisit of the Chebyshev (equiripple) and Papoulis (monotonic or staircase) low-pass filter in order to compare. It can be stated the fair comparison of Papoulis and Chebyshev filters cannot be found in the available ...

Chebyshev series: Derivation and evaluation
PLoS ONE, 2023 In this paper we use a contour integral method to derive a bilateral generating function in the form of a double series involving Chebyshev polynomials expressed in terms of the incomplete gamma function. Generating functions for the Chebyshev polynomial

Extension of the Chebyshev Method of Quassi-Linear Parabolic P.D.E.S With Mixed Boundary Conditions
مجلة بغداد للعلوم, 2009 The researcher [1-10] proposed a method for computing the numerical solution to quasi-linear parabolic p.d.e.s using a Chebyshev method. The purpose of this paper is to extend the method to problems with mixed boundary conditions.

Recurrence relations for Chebyshev-type methods. [PDF]
, 2000 The convergence of new second-order iterative methods are analyzed in Banach spaces by introducing a system of recurrence relations. A system of a priori error bounds for that method is also provided.

A Spectral Method for Two-Dimensional Ocean Acoustic Propagation
Journal of Marine Science and Engineering, 2021 The accurate calculation of the sound field is one of the most concerning issues in hydroacoustics. The one-dimensional spectral method has been used to correctly solve simplified underwater acoustic propagation models, but it is difficult to solve ...

Reduced Recurrence Relations for the Chebyshev Method. [PDF]
, 1998 In this paper, we give sufficient conditions ensuring the convergence of the Chebyshev method in Banach spaces. We use a new system of recurrence relations which simplifies those given by Kantorovich for the Newton method or those given by Candela and ...

(Beta, Gamma) - Chebyshev functions and theirs application to the Gibbs and Runge phenomenons
, 2022 openIn questo elaborato presentiamo le (β, γ)-funzioni di Chebyshev e i corrispondenti (β, γ)-punti di Chebyshev. Mostriamo che possono essere considerati come una gene- ralizzazione dei polinomi di Chebyshev, analizzando le loro proprietà piu ...
