摘要
当a≥0,b∈R(实数集),序列{xn(a,b)},n=1,2,…何时为实数序列?该序列的增减性如何?其极限是什么?本文对以上问题给出了全面讨论;最后是此种根式迭代的一般形式.
Abstract
When is the sequence {xn(a,b)},n=1,2,…a real number sequence?How does the sequence in-crease or decrease?What is the limit?This paper discusses these problems,and gives the general form of this radical iteration.
