摘要
利用组合证明的方法研究了与正整数的有序分拆的分部量1相关的恒等式.首先给出了正整数有序分拆的分部量1有两种形式的一个恒等式.其次得到了几个关于正整数的分部量是1或者2的有序分拆数以及回文的有序分拆数的In-place恒等式.
In this paper,we studied identities related to the part 1 for compositions of positive integers using the combinatorial proof method.We first present an identity for the number of compositions when the part 1 can be of two kinds.And then we obtain several new In-place identities for the numbers of 1-2 compositions and palindromic compositions.
