Order of the Runge-Kutta Method and Evolution of the Stability Region

In this article, we demonstrate through specific examples that the evolution of the size of the absolute stability regions of Runge–Kutta methods for ordinary differential equation does not depend on the order of methods.We would like to express our deepest appreciation and gratitude to Professor Sergey Khashin of Ivanovo State University who provided us the possibility to coordinate and complete this article
