Arithmetic properties of $2^\alpha-$Regular overpartition pairs

Number Theory 2025-02-25 v1

Abstract

Recently, several mathematicians have investigated various partition functions with the goal of discovering Ramanujan-type congruences. One such function is B2α(n)\overline{B}_{2^\alpha}(n), which represents the number of 2α2^\alpha-regular overpartition pairs of nn. In this context, we establish Ramanujan-type congruences modulo powers of 22 for this function. For instance, we prove that \begin{equation*} \overline{B}_{2^{\alpha}}(2^{\alpha+\beta+1}(n+1)) \equiv 0\pmod{2^{3\beta+5}} \end{equation*} for all n,β0,αNn, \beta\geq 0,\, \alpha \in \mathbb{N}.
