Linear Stability Analysis of Runge-Kutta Methods for Singular Lane-Emden Equations

open access: yesJournal of Nigerian Society of Physical Sciences, 2020
Runge-Kutta methods are efficient methods of computations in differential equations, the classical Runge-Kutta method of order 4 happens to be the most popular of these methods, and most times it is attached to the mind when Runge-Kutta methods are ...

Stochastic Runge–Kutta methods for multi-dimensional Itô stochastic differential algebraic equations

open access: yesResults in Applied Mathematics, 2021
In this paper, we discuss the numerical solutions to index 1 stochastic differential algebraic equations. We introduce a new class of weak second-order stochastic Runge–Kutta methods for finding the numerical approximate solutions to multi-dimensional ...

Optimal monotonicity-preserving perturbations of a given Runge-Kutta method [PDF]

open access: yes, 2018
Perturbed Runge--Kutta methods (also referred to as downwind Runge--Kutta methods) can guarantee monotonicity preservation under larger step sizes relative to their traditional Runge--Kutta counterparts.

Extrapolated Implicit–Explicit Runge–Kutta Methods

open access: yesMathematical Modelling and Analysis, 2014
We investigate a new class of implicit–explicit singly diagonally implicit Runge–Kutta methods for ordinary differential equations with both non-stiff and stiff components. The approach is based on extrapolation of the stage values at the current step by

Global error estimation of linear multistep methods through the Runge-Kutta methods [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2016
In this paper, we study the global truncation error of the linear multistep methods (LMM) in terms of local truncation error of the corresponding Runge-Kutta schemes. The key idea is the representation of LMM with a corresponding Runge-Kutta method.
