From Wikipedia, the free encyclopedia
In mathematics, Esenin-Volpin's theorem states that weight of an infinite compact dyadic space is the supremum of the weights of its points. It was introduced by Alexander Esenin-Volpin (1949).[1] It was generalized by Efimov in 1965[2] and Turzański in 1992.[3]
