Rogers-Ramanujan type identities and Chebyshev Polynomials of the third kind

Lisa H. Sun

It is known that $q$ -orthogonal polynomials play an important role in the field of $q$ -series and special functions. During studying Dyson's "favorite" identity of Rogers--Ramanuja…

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…

Zigzag Stacks and m-Regular Linear Stacks

William Y. C. Chen, Qiang-Hui Guo, Lisa H. Sun +1

The contact map of a protein fold is a graph that represents the patterns of contacts in the fold. It is known that the contact map can be decomposed into stacks and queues. RNA se…

An Iterated Map for the Lebesgue Identity

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

We present a simple iteration for the Lebesgue identity on partitions, which leads to a refinement involving the alternating sums of partitions.
