In mathematics, a dyadic compactum is a Hausdorff topological space that is the continuous image of a product of discrete two-point spaces, [1] and a dyadic space is a topological space with a compactification which is a dyadic compactum. [2] However, many authors use the term dyadic space with the same meaning as dyadic compactum above. [3] [4] [5]
Dyadic compacta and spaces satisfy the Suslin condition, and were introduced by Russian mathematician Pavel Alexandrov. [1] Polyadic spaces are generalisation of dyadic spaces. [5]
