Abstract

In this paper, we study the partition function \(p_{[c^{l}d^{m}]}(n)\) defined by \(\sum_{n=0}^{\infty}p_{[c^{l}d^{m}]}(n)q^{n}=(q^{c};q^{c})_{\infty}^{-l}(q^{d};q^{d})_{\infty}^{-m}\) and prove some analogues of Ramanujan’s partition identities. We also deduce some interesting partition congruences.
