AI总结:

基于四阶代数精度的两级隐式Runge-Kutta方法Gauss,提出一种零色散方法和一种零色散零耗散方法,通过求解径向薛定谔方程等初值问题验证其效率。

摘要:

本文提出了两种基于隐式Runge-Kutta方法Gauss的新方法,该方法具有四阶代数精度和两个阶段:第一种方法具有零色散,第二种方法具有零色散和零耗散。在求解径向薛定谔方程和其他已知初值问题时,衡量了这些方法的效率。

英文摘要:

In this paper we present two new methods based on an implicit Runge-Kutta method Gauss which is of algebraic order fourth and has two stages: the first one has zero dispersion and the second one has zero dispersion and zero dissipation. The efficiency of these methods is measured while integrating the radial Schrödinger equation and other well known initial value problems.
