Refined Wilf-equivalences by Comtet statistics

Shishuo Fu, Zhicong Lin, Yaling Wang

We launch a systematic study of the refined Wilf-equivalences by the statistics $comp$ and $iar$ , where $comp (π)$ and $iar (π)$ are the number of…

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…
