Abstract

In the theory of partitions, Euler’s partition theorem involving odd parts and different parts is one of the famous theorems. It states that the number of partitions of an integer n into odd parts is equal to the number of partitions of n into different parts. By intepretting odd parts as parts congruent to 1 modulo 2, the second author and Keith provided a completely generalization about Euler’s partition theorem involving odd parts and different parts for all moduli and provide new companions to Rogers-Ramanujan-Andrews-Gordon identities related to this theorem. They gave a combinatorial proof of the theorem by establishing bijection. In this note, we will offer an anclytic view point of this beautiful theorem. We use q-series and generating function theories to provide an analytic style proof for some cases of Keith-Xiong’s theorem. By defining basic units and special units, the basic units in the partitions are divided into two categories, and then the number between the basic units in the special units is classified, and all the cases when m = 3 and alternative sum type (Σ,2) are given, our method is verifying the generating functions of both sides satisfying the same recurrences.
