On Bilateral Multiple Sums and Rogers-Ramanujan Type Identities

Dandan Chen, Tianjian Xu

We establish some new bilateral double-sum Rogers-Ramanujan identities involving parameters. As applications, these identities yield several new multi-sum Rogers-Ramanujan type ide…

Congruences modulo powers of for generalized Frobenius partitions

Dandan Chen, Siyu Yin

In 1984, Andrews introduced the family of partition functions \(cϕ_k(n)\), which counts the number of generalized Frobenius partitions of \(n\) with \(k\) colors. In previous work…

Congruences modulo powers of for -elongated plane partitions

Dandan Chen, Tianjian Xu, Siyu Yin

The enumeration of -elongated plane partition diamonds has emerged as a generalization of the classical integer partition function . Congruences for modu…
