An infinite family of overpartition congruences mod powers of 2
Zhumagali Shomanov, Frank Garvan
We prove an infinite family of Hecke-like congruences for the overpartition function modulo powers of 2. Starting from a recent identity of Garvan and Morrow and iterating Atkin's…

A simple proof of the Atkin-O'Brien partition congruence conjecture for powers of 13
Frank Garvan, Zhumagali Shomanov
In 1967, Atkin and O'Brien conjectured congruences for the partition function involving Hecke operators modulo powers of 13. In this paper, we provide a simple proof of this conjec…
