摘要: 利用Agarwal的组合方法研究了几个新的与正整数的有序分拆和无序分拆相关的Euler型恒等式,得到了正整数的奇-偶有序分拆数和奇-奇-偶-偶无序分拆数之间以及偶-奇有序分拆数和偶-奇-奇-偶无序分拆数之间的恒等关系,同时给出了2类有序分拆数的递推关系,研究了一类限定部分量的有序分拆数的恒等式.Abstract: Some new Euler identities between partitions and compositions of positive integers are studied. The identical relation between odd-even composition and odd-odd-even-even partition, and the identical relation between even-odd composition and even-odd-odd-even partition are obtained. Furthermore, the recurrences between two types of compositions are given. The identities of composition that parts are limited are studied also.
