4 unusual facts about Hilbert cube


Hilbert cube

In mathematics, the Hilbert cube, named after David Hilbert, is a topological space that provides an instructive example of some ideas in topology.

Conversely, every Polish space is homeomorphic to a Infinite-dimensional Lebesgue measure

Compact sets in Banach spaces may also carry natural measures: the Hilbert cube, for instance, carries the product Lebesgue measure.

Richard Davis Anderson

Much of his early work focused on proofs surrounding Hilbert space and Hilbert cubes.

Exterior space

Shape theory: Many shape invariants (Borsuk groups, Quigley inward and approaching groups) of a compact metric space can be obtained as exterior homotopy groups of the exterior space determined by the open neighborhoods of a compact metric space embedded in the Hilbert cube.
