A class of algorithms for rational approximation of functions formally defined by power series [PDF]

, 1972
Corresponding sequence algorithms are defined and shown to exist for a wide range of corresponding continued fractions. Particular examples of these algorithms are given, including an algorithm for forming Pade approximants, and an error analysis is ...

Schwinger functions and light-quark bound states

, 2007
We examine the applicability and viability of methods to obtain knowledge about bound-states from information provided solely in Euclidean space. Rudimentary methods can be adequate if one only requires information about the ground and first excited ...

Multiderivative methods for periodic initial value problems [PDF]

, 1982
A family of two-step multiderivative methods based on Pade approximants to the exponential function is developed. The methods are analysed and periodicity intervals in PECE mode are calculated.

Dynamics and Fractal Dimension of Steffensen-Type Methods

Algorithms, 2015
In this paper, the dynamical behavior of different optimal iterative schemes for solving nonlinear equations with increasing order, is studied. The tendency of the complexity of the Julia set is analyzed and referred to the fractal dimension.

Modified two-dimensional differential transform method for solving proportional delay partial differential equations

Results in Control and Optimization
In this study, we develop a modified version of the two-dimensional differential transform (TDDT) method for solving proportional delay partial differential equations (PDPDEs) that frequently arise in engineering and scientific models.

An optimal fourth-order family of modified Cauchy methods for finding solutions of nonlinear equations and their dynamical behavior

Open Mathematics, 2019
In this paper, we derive and analyze a new one-parameter family of modified Cauchy method free from second derivative for obtaining simple roots of nonlinear equations by using Padé approximant.

Theoretical Characterization of Latencies in the Wide-Synchronization Control for Oscillations Damping

Electricity
Wide-area damping controls, like the wide-synchronization control (WSC), are crucial for power system stability but are vulnerable to communication latencies. This article presents a comprehensive theoretical characterization of the impact of time delays
