Description

The maximal sum of entries on a diagonal of an alternating sign matrix.
For example, the sums of the diagonals of the matrix

$\left(\begin{array}{rrrr} 0 & 0 & 1 & 0 \\ 0 & 1 & 0 & 0 \\ 1 & 0 & -1 & 1 \\ 0 & 0 & 1 & 0 \end{array}\right)$
are

$(0,1,1,0,1,1,0)$ , so the statistic is

$1$ .
This is a natural extension of St000887The maximal number of nonzero entries on a diagonal of a permutation matrix. to alternating sign matrices.

bounce path

Description

The bounce path determined by an integer composition.

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

to symmetric ASM

Description

The diagonally symmetric alternating sign matrix corresponding to a Dyck path.
