Abstract

Let $n$ and $t$ be positive integers with $t\geq 2$. Let $R_t(n)$ be the number of $t$-regular partitions of $n$. A class of functions, denoted $\tau_k(n)$, is defined as follows: \[q\prod_{m=1}^{\infty}(1-q^m)^k=\sum_{n=1}^{\infty}\tau_k(n)q^n, \] where $k$ is an integer. We express $\tau_k(n)$ as a binomial coefficient weighted partition sum. Consequently, we obtain congruence identities that relate $\tau_k(n)$, $R_t(n)$ and partition function weighted composition sums.
