An improvement of the Euler–Chebyshev iterative method
Journal of Mathematical Analysis and Applications, 2006 The computation of a simple root of a sufficiently smooth scalar function \(f\) is discussed. The Newton method and the Euler-Chebyshev method are briefly presented. A method based on the Euler-Chebyshev method using a linear combination of function values of \(f\) with a convergence order of 5 is constructed.

Fractal and FractionalThe current article introduces a Petrov–Galerkin method (PGM) to address the fourth-order uniform Euler–Bernoulli pinned–pinned beam equation. Utilizing a suitable combination of second-kind Chebyshev polynomials as a basis in spatial variables, the ...

Initial approximations in Euler-Chebyshev's method
Journal of Computational and Applied Mathematics, 1995 The author considers a polynomial \(f(x)\) of degree \(n\) and the Euler-Chebyshev iterative method for approximating its zeros. He proves that for any monic polynomial \(f(x)\) of degree \(n\), there exists a set \(\Gamma_f\subset \mathbb{C}^n\) such that the Euler-Chebyshev method starting from \(x^0= x\in \Gamma_f\) does not converge to the zeros of

Wilkinson Polynomials: Accuracy Analysis Based on Numerical Methods of the Taylor Series Derivative
Desimal, 2020 Some of the numeric methods for solutions of non-linear equations are taken from a derivative of the Taylor series, one of which is the Newton-Raphson method. However, this is not the only method for solving cases of non-linear equations.

High order iterative methods for decomposition‐coordination problems
Technological and Economic Development of Economy, 2006 Many real‐life optimization problems are of the multiobjective type and highdimensional. Possibilities for solving large scale optimization problems on a computer network or multiprocessor computer using a multi‐level approach are studied.

A semilocal convergence analysis for the method of tangent parabolas
Journal of Numerical Analysis and Approximation Theory, 2005 We present a semilocal convergence analysis for the method of tangent parabolas (Euler-Chebyshev) using a combination of Lipschitz and center Lipschitz conditions on the Fréchet derivatives involved.

Monetary Policy When Preferences Are Quasi‐Hyperbolic
Journal of Money, Credit and Banking, EarlyView.Abstract We study discretionary monetary policy in an economy where economic agents have quasi‐hyperbolic discounting. We demonstrate that a benevolent central bank is able to keep inflation under control for a wide range of discount factors. If the central bank, however, does not adopt the household's time preferences and tries to discourage early ...

What If Each Voxel Were Measured With a Different Diffusion Protocol?
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2277-2290, April 2026.ABSTRACT Purpose Expansion of diffusion MRI (dMRI) both into the realm of strong gradients and into accessible imaging with portable low‐field devices brings about the challenge of gradient nonlinearities. Spatial variations of the diffusion gradients make diffusion weightings and directions non‐uniform across the field of view, and deform perfect ...
