摘要: k的值不大时(例如k≤4),诸系数γiγi*,β,β*易于手工计算。但对大的k值(例如k≥5),手工计算已非易事。利用著名的计算机代数软件:REDUCE[a],我们可以很容易地计算出诸系数γi,γi*,β,β*

Abstract: In this paper, the coefficients γi, γi,,βkp and βkp in the explicit and implicit Adams integration schemes (1) and (2) are calculated for 0 ≤ j,k ≤ 9 using REDUCE.lt is pointed out that there were some errors in the tabulated values of β5p in Refs.[1] and[2].
