Rowmotion on the chain of V's poset and whirling dynamics
Matthew Plante, Tom Roby
Given a finite poset , we study the _whirling_ action on vertex-labelings of with the elements . When such labelings are (weakly) order-reversing, we ca…

Rowmotion on fences
Sergi Elizalde, Matthew Plante, Tom Roby +1
A fence is a poset with elements F = {x_1, x_2, ..., x_n} and covers x_1 < x_2 < ... < x_a > x_{a+1} > ... > x_b < x_{b+1} < ... where a, b, ... are positive integers. We investiga…
