Enumerations for Permutations by Circular Peak Sets

Pierre Bouchard, Hungyung Chang, Jun Ma +1

The circular peak set of a permutation $σ$ is the set ${σ (i) ∣ σ (i - 1) < σ (i) > σ (i + 1)}$ . In this paper, we focus on the enumeration problems for permutations by circular peak sets.…

Circular Peaks and Hilbert Series

Pierre Bouchard, Jun Ma, Yeong-Nan Yeh

The circular peak set of a permutation $σ$ is the set ${σ (i) ∣ σ (i - 1) < σ (i) > σ (i + 1)}$ . Let $P_{n}$ be the set of all the subset $S \subseteq [n]$ such that there exists a…
