A new decomposition of ascent sequences and Euler--Stirling statistics

Shishuo Fu, Emma Yu Jin, Zhicong Lin +2

As shown by Bousquet-Mélou--Claesson--Dukes--Kitaev (2010), ascent sequences can be used to encode $(2 + 2)$ -free posets. It is known that ascent sequences are enumerated by the…

Bijective recurrences concerning two Schröder triangles

Shishuo Fu, Yaling Wang

Let $r (n, k)$ (resp. $s (n, k)$ ) be the number of Schröder paths (resp. little Schröder paths) of length $2 n$ with $k$ hills, and set $r (0, 0) = s (0, 0) = 1$ . We bijectively establish the f…

A lecture hall theorem for $m$ -falling partitions

Shishuo Fu, Dazhao Tang, Ae Ja Yee

For an integer $m \geq 2$ , a partition $λ = (λ_{1}, λ_{2}, \dots)$ is called $m$ -falling, a notion introduced by Keith, if the least nonnegative residues mod $m$ of $λ_{i}$ 's form a nonincrea…
