Dyadic space

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by Paolo Lipparini (talk | contribs) at 20:58, 31 January 2016 (the source says that not every subspace of a dyadic compactum is a dyadic compactum, so this is a different definition). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

In mathematics, a dyadic compactum is a Hausdorff topological space that is the continuous image of a product of discrete two-point sets,[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]
