Reversion of Chebyshev’s Inequality

Theory of Probability & Its Applications, 1996
Summary: In terms of the moment-generating function of a random variable, we derive a lower bound for the tail of its distribution without an excursion into the complex domain.

Chebyshev rational interpolation

Numerical Algorithms, 1997
Denote by \(E_\rho\), \(0 \leq \rho \leq 1\), the closed ellipse in \(\mathbb C\) with the boundary \[ \partial E_\rho = \{ t+ \rho t^{-1}:\;|t|=1 \}, \] and \[ s_j(z)=w^j+(\rho/w)^j, \quad z=w+\rho/w, \quad j=2, \dots, \] the corresponding Chebyshev polynomials. The paper faces the problem of the efficient computation of all the rational functions \[ \

Chebyshev and Modified Chebyshev Filters

2019
Chebyshev (C) filters are among the most frequently used. Their transfer function is obtained via the characteristic function (which is introduced in this chapter) to offer the most selective polynomial filters of all. In addition, their amplitude characteristic in the passband is equi-ripple.

Chebyshev Spaces of Polynomials

SIAM Journal on Numerical Analysis, 1976
Spaces of polynomials of degrees $ \leqq n - 1$ which satisfy $r < n$ interpolatory conditions of the form $p^{(j)} (\xi _i ) = 0$ are discussed. Necessary and sufficient conditions for such spaces to be Chebyshev spaces are given.

A note on Chebyshev polynomials

ANNALI DELL UNIVERSITA DI FERRARA, 2001
Here new families of generating functions and identities concerning the Chebyshev polynomials are derived. It is shown that the proposed method allows the derivation of sum rules involving products of Chebyshev polynomials and addition theorems. The possibility of extending the results to include generating functions involving products of Chebyshev and

Chebyshev Approximation by Exponentials

Journal of the Society for Industrial and Applied Mathematics, 1962
are considered. For n = 1 the theory is given in [3]. The principal theoretical questions of existence, uniqueness and characterization of best approximations are answered for this approximating function. The problem of the computation of best approximations is unsolved.

Chebyshev–Schoenberg Operators

Constructive Approximation, 2010
The present paper generalizes the results of \textit{M.-L. Mazure} [Numer. Algorithms 52, No. 1, 93--128 (2009; Zbl 1200.41023)] to Schoenberg-type operators. It is shown that a given spline space based on a given extended Chebyshev space gives birth to infinitely many variation-diminishing operators of Schoenberg-type, characterized by the two ...
