Butcher group

The term "Butcher group" primarily refers to the mathematical structure known as the "Butcher group" in the context of numerical analysis, particularly in the field of solving ordinary differential equations (ODEs) using Runge-Kutta methods. Runge-Kutta methods are iterative techniques used to obtain numerical solutions to ODEs. The Butcher group specifically deals with the coefficients and structure of these methods. Named after the mathematician John C.
