Description

The projective dimension of the simple modules corresponding to the minimum of L in the incidence algebra of the lattice L.

Map

antichains of maximal size

Description

The lattice of antichains of maximal size in a poset.
The set of antichains of maximal size can be ordered by setting

$A \leq B \leftrightarrow \mathop{\downarrow} A \subseteq \mathop{\downarrow} B$ , where

$\mathop{\downarrow} A$ is the order ideal generated by

$A$ .
This is a sublattice of the lattice of all antichains with respect to the same order relation. In particular, it is distributive.

Map

peaks-to-valleys

Description

Return the path that has a valley wherever the original path has a peak of height at least one.
More precisely, the height of a valley in the image is the height of the corresponding peak minus

$2$ .
This is also (the inverse of) rowmotion on Dyck paths regarded as order ideals in the triangular poset.

Map

Hessenberg poset

Description

The Hessenberg poset of a Dyck path.
Let

$D$ be a Dyck path of semilength

$n$ , regarded as a subdiagonal path from

$(0,0)$ to

$(n,n)$ , and let

$\boldsymbol{m}_i$ be the

$x$ -coordinate of the

$i$ -th up step.
Then the Hessenberg poset (or natural unit interval order) corresponding to

$D$ has elements

$\{1,\dots,n\}$ with

$i < j$ if

$j < \boldsymbol{m}_i$ .
