Description

The injective dimension of the tensor product of two copies of the dual of the Nakayama algebra associated to a Dyck path.
Here

$A$ is the Nakayama algebra associated to a Dyck path as given in DyckPaths/NakayamaAlgebras.

Map

Cori-Le Borgne involution

Description

The Cori-Le Borgne involution on Dyck paths.
Append an additional down step to the Dyck path and consider its (literal) reversal. The image of the involution is then the unique rotation of this word which is a Dyck word followed by an additional down step. Alternatively, it is the composite

$\zeta\circ\mathrm{rev}\circ\zeta^{(-1)}$ , where

$\zeta$ is Mp00030zeta map.

Map

parallelogram polyomino

Description

Return the Dyck path corresponding to the partition interpreted as a parallogram polyomino.
The Ferrers diagram of an integer partition can be interpreted as a parallogram polyomino, such that each part corresponds to a column.
This map returns the corresponding Dyck path.

Map

Elizalde-Deutsch bijection

Description

The Elizalde-Deutsch bijection on Dyck paths.
.Let

$n$ be the length of the Dyck path. Consider the steps

$1,n,2,n-1,\dots$ of

$D$ . When considering the

$i$ -th step its corresponding matching step has not yet been read, let the

$i$ -th step of the image of

$D$ be an up step, otherwise let it be a down step.
