WebFeb 8, 2024 · It is variously denoted by QQor IωI^\omega. It plays a central role in Borsuk's shape theory, and is the basis for the construction of Hilbert cube manifolds. The theory of these were developed by Tom Chapman (mid 1970s) and were used in his proof of the topological invariance of Whitehead torsion.

WebNov 11, 2024 · This is a numpy-based implementation of Hilbert curves, for up to a few tens of dimensions. A Hilbert curve is a continuous space-filling curve that lets you map from a single dimension into multiple dimensions. In two dimensions, you get curves that look like this: cube reflects the number of bits per dimension. You could normalize this to put.

Furthermore, many interesting topological spaces can be embedded in the Hilbert cube; that is, can be viewed as subspaces of the Hilbert cube (see below). See more It is sometimes convenient to think of the Hilbert cube as a metric space, indeed as a specific subset of a separable Hilbert space (that is, a Hilbert space with a countably infinite Hilbert basis). For these purposes, it is best … See more As a product of compact Hausdorff spaces, the Hilbert cube is itself a compact Hausdorff space as a result of the Tychonoff theorem.
