Complexes of pattern-avoiding injective words

Sergi Elizalde, Philip Hanlon, Patricia Hersh

The complex of injective words is a cell complex that arises in a number of different areas. It has applications to proving homological stability and to the study of group cohomolo…

On individual leaf depths of trees

Sergi Elizalde

We explore a generating function trick which allows us to keep track of infinitely many statistics using finitely many variables, by recording their individual distributions rather…

Rowmotion on 321-avoiding permutations

Ben Adenbaum, Sergi Elizalde

We give a natural definition of rowmotion for -avoiding permutations, by translating, through bijections involving Dyck paths and the Lalanne--Kreweras involution, the analogo…

Partitions with constrained ranks and lattice paths

Sylvie Corteel, Sergi Elizalde, Carla Savage

In this paper we study partitions whose successive ranks belong to a given set. We enumerate such partitions while keeping track of the number of parts, the largest part, the side…

On a dart game of Niedermaier

Sergi Elizalde

We analyze a game introduced by Andy Niedermaier, where players take turns throwing a dart at a dartboard. A player is eliminated unless his dart lands closer to the center tha…

Statistics on clusters and -Stirling permutations

Sergi Elizalde, Justin M. Troyka, Yan Zhuang

The Goulden$\unicode{x2013}$Jackson cluster method, adapted to permutations by Elizalde and Noy, reduces the problem of counting permutations by occurrences of a prescribed consecu…
