Runge–Kutta methods and renormalization [PDF]

open access: yesThe European Physical Journal C, 2000
A connection between the algebra of rooted trees used in renormalization theory and Runge-Kutta methods is pointed out. Butcher's group and B-series are shown to provide a suitable framework for renormalizing a toy model of field the ory, following Kreimer's approach.

On Adaptive Patankar Runge–Kutta methods [PDF]

open access: yesPAMM, 2021
AbstractWe apply Patankar Runge–Kutta methods to y′ = M(y)y and focus on the case where M(y) is a graph Laplacian as the resulting scheme will preserve positivity and total mass. The second order Patankar Heun method is tested using four test problems (stiff and non‐stiff) cast into this form.

Zero-dissipative explicit Runge-Kutta method for periodic initial value problems [PDF]

open access: yes, 2014
In this paper zero-dissipative explicit Runge-Kutta method is derived for solving second-order ordinary differential equations with periodical solutions. The phase-lag and dissipation properties for Runge-Kutta (RK) method are also discussed.

Low storage explicit Runge-Kutta method

open access: yesSemina: Ciências Exatas e Tecnológicas, 2019
This paper we are dealing with the high order accurate low storage explicit Runge Kutta (LSERK) methods which mainly are used for temporal discretization and are stable regardless of its accuracy.

A class of implicit-explicit two-step Runge-Kutta methods [PDF]

open access: yes, 2012
This work develops implicit-explicit time integrators based on two-step Runge-Kutta methods. The class of schemes of interest is characterized by linear invariant preservation and high stage orders.
