Description

The number of entries equal to -1 in an alternating sign matrix.
The number of nonzero entries, St000890The number of nonzero entries in an alternating sign matrix. is twice this number plus the dimension of the matrix.

Map

to alternating sign matrix

Description

Return the Dyck path as an alternating sign matrix.
This is an inclusion map from Dyck words of length $2n$ to certain
$n \times n$ alternating sign matrices.

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.
