Kuratowski embedding

Kuratowski embedding is a concept in topology associated with the work of the Polish mathematician Kazimierz Kuratowski. It refers to a method of embedding a given topological space into a Hilbert space (or sometimes into Euclidean space) in a way that preserves certain properties of the space. More specifically, the Kuratowski embedding theorem states that any metrizable topological space can be embedded into a complete metric space.
