Arithmetic properties of generalized cubic and overcubic partitions

Abstract

We prove several congruences satisfied by the generalized cubic and generalized overcubic partition functions, recently introduced by Amdeberhan, Sellers, and Singh. We also prove infinite families of congruences modulo powers of 2 and modulo 12 satisfied by the generalized overcubic partitions, as well as some density results that they satisfy. We use both elementary q-series techniques as well as the theory of modular forms to prove our results. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2026.
