On $(2 k + 1, 2 k + 3)$ -core partitions with distinct parts

Sherry H. F. Yan, Guizhi Qin, Zemin Jin +1

In this paper, we are mainly concerned with the enumeration of $(2 k + 1, 2 k + 3)$ -core partitions with distinct parts. We derive the number and the largest size of such partitions, con…

Ordered Partitions Avoiding a Permutation of Length 3

William Y. C. Chen, Alvin Y. L. Dai, Robin D. P. Zhou

An ordered partition of $[n] = {1, 2, \dots, n}$ is a partition whose blocks are endowed with a linear order. Let $O P_{n, k}$ be set of ordered partitions of $[n]$ with $…

On Pattern Avoiding Alternating Permutations

Joanna N. Chen, William Y. C. Chen, Robin D. P. Zhou

An alternating permutation of length $n$ is a permutation $π = π_{1} π_{2} ... π_{n}$ such that $π_{1} < π_{2} > π_{3} < π_{4} > ...$ . Let $A_{n}$ denote set of alternating permutations of ${1,2,...…
