Description

The box weight or horizontal decoration of a Dyck path.
Let a Dyck path

$D = (d_1,d_2,\dots,d_n)$ with steps

$d_i \in \{N=(0,1),E=(1,0)\}$ be given.
For the

$i$ th step

$d_i \in D$ we define the weight

$\beta(d_i) = 1, \quad \text{ if } d_i=N,$
and

$\beta(d_i) = \sum_{k = 1}^{i} [\![ d_k = N]\!], \quad \text{ if } d_i=E,$
where we use the Iverson bracket

$[\![ A ]\!]$ that is equal to

$1$ if

$A$ is true, and

$0$ otherwise.
The box weight or horizontal deocration of

$D$ is defined as

$\prod_{i=1}^{n} \beta(d_i).$
The name describes the fact that between each

$E$ step and the line

$y=-1$ exactly one unit box is marked.

Description

The reversal of a Dyck path.
This is the Dyck path obtained by reading the path backwards.
