Ramanujan-type Congruences for Overpartitions Modulo 16

William Y. C. Chen, Qing-Hu Hou, Lisa H. Sun +1

Let $p (n)$ denote the number of overpartitions of $n$ . Recently, Fortin-Jacob-Mathieu and Hirschhorn-Sellers independently obtained 2-, 3- and 4-dissections of the gener…

Ramanujan-type Congruences for Overpartitions Modulo 5

William Y. C. Chen, Lisa H. Sun, Rong-Hua Wang +1

Let $p (n)$ denote the number of overpartitions of $n$ . Hirschhorn and Sellers showed that $p (4 n + 3) \equiv 0 (mod 8)$ for $n \geq 0$ . They also conjectured that…
