A combinatorial duality between the weak and strong Bruhat orders
Christian Gaetz, Yibo Gao
In recent work, the authors used an order lowering operator , introduced by Stanley, to prove the strong Sperner property for the weak Bruhat order on the symmetric group.…

A combinatorial -action and the Sperner property for the weak order
Christian Gaetz, Yibo Gao
We construct a simple combinatorially-defined representation of which respects the order structure of the weak order on the symmetric group. This is used to resol…

Path counting and rank gaps in differential posets
Christian Gaetz, Praveen Venkataramana
We study the gaps between consecutive rank sizes in -differential posets by introducing a projection operator whose matrix entries can be expressed in terms of the number…
