Description

The number of factors of a standard tableaux under concatenation. The concatenation of two standard Young tableaux

$T_1$ and

$T_2$ is obtained by adding the largest entry of

$T_1$ to each entry of

$T_2$ , and then appending the rows of the result to

$T_1$ , see [1, dfn 2.10]. This statistic returns the maximal number of standard tableaux such that their concatenation is the given tableau.

Description

The number of topologically connected components of a set partition. For example, the set partition

$\{\{1,5\},\{2,3\},\{4,6\}\}$ has the two connected components

$\{1,4,5,6\}$ and

$\{2,3\}$ . The number of set partitions with only one block is [[oeis:A099947]].

Description

The number of global descents of a permutation. The global descents are the integers in the set

$C(\pi)=\{i\in [n-1] : \forall 1 \leq j \leq i < k \leq n :\quad \pi(j) > \pi(k)\}.$ In particular, if

$i\in C(\pi)$ then

$i$ is a descent. For the number of global ascents, see [[St000234]].
