Directed set: Examples, Overview & Directed subsets

In mathematics, a directed set (or a directed preorder or a filtered set) is a preordered set in which every finite subset has an upper bound. In other words, it is a non-empty preordered set A {\displaystyle A} such that for any a {\displaystyle a} and b {\displaystyle b} in A {\displaystyle A} there exists c {\displaystyle c} in A {\displaystyle A}…
