Definition:Ordered Set of Increasing Mappings

Definition
Let $L = \struct{S_1, \preceq_1}$, $K = \struct{S_2, \preceq_2}$ be ordered sets.

The ordered set of increasing mappings from $K$ into $L$ is ordered subset of $L^{S_2} = \struct{S_1^{S_2}, \preceq'}$ and is defined by
 * $\map {\operatorname{Increasing}} {K, L} = \struct{X, \precsim}$

where
 * $X = \leftset {f:S_2 \to S_1: f}$ is increasing mapping$\rightset{}$
 * $\mathord\precsim = \mathord\preceq' \cap \paren{X \times X}$
 * $L^{S_2}$ denotes the ordered set of all mappings from $S_2$ into $L$,
 * $S_1^{S_2}$ denotes the set of all mappings from $S_2$ into $S_1$.

$\map {\operatorname{Increasing}} {K, L}$ as ordered subset of ordered set is ordered set by Ordered Subset of Ordered Set is Ordered Set.
