Dyadic space
In mathematics, a dyadic compactum is a Hausdorff topological space that is the continuous [function (topology)|continuous] image of a product of discrete [two-point space]s, and a dyadic space is a topological space with a compactification which is a dyadic compactum. However, many authors use the term dyadic space with the same meaning as dyadic compactum above.
Dyadic compacta and spaces satisfy the Countable [chain condition|Suslin condition], and were introduced by Russian mathematician Pavel Alexandrov. Polyadic spaces are generalisation of dyadic spaces.
