Description

The projective dimension of the first term in an injective coresolution of the regular module.
The algebra has the double centraliser property when 0 is returned and it is 1-Gorenstein in case a number < =1 is returned.

Map

bounce path

Description

Sends a Dyck path

$D$ of length

$2n$ to its bounce path.
This path is formed by starting at the endpoint

$(n,n)$ of

$D$ and travelling west until encountering the first vertical step of

$D$ , then south until hitting the diagonal, then west again to hit

$D$ , etc. until the point

$(0,0)$ is reached.
This map is the first part of the zeta map Mp00030zeta map.

Map

prime Dyck path

Description

Return the Dyck path obtained by adding an initial up and a final down step.

Map

promotion

Description

The promotion of the two-row standard Young tableau of a Dyck path.
Dyck paths of semilength

$n$ are in bijection with standard Young tableaux of shape

$(n^2)$ , see Mp00033to two-row standard tableau.
This map is the bijection on such standard Young tableaux given by Schützenberger's promotion. For definitions and details, see [1] and the references therein.
