This relationship has been known since 1937, based on a work by Pavel Alexandrov, however its application and theoretical and practical meaning is apparently not very widespread. Perhaps it is because of the simplicity of these spaces, none of them, except the trivial ones, are no more than T0 spaces. However, the current boom in data AI and other computational methods could make us think about its probable importance (and its relation to Algebraic Topology).
It would be interesting to know, for example, the relations of hypercube with the corresponding finite topological spaces.

1. Finite topological spaces can model discrete data structures, such as graphs, networks, and point clouds. Their correspondence with polyhedra allows for the application of topological data analysis (TDA) techniques, such as persistent homology, to study the shape and structure of data.
2. Hypercubes, which are fundamental in computer science and data representation, can be studied as finite topological spaces. Their associated topologies provide insights into the connectivity and hierarchical structure of data, which is relevant for machine learning and optimization.
- Finite topological spaces can be associated with simplicial complexes, which are central to algebraic topology. This allows for the computation of topological invariants, such as Betti numbers and Euler characteristics, using combinatorial methods.
- Homotopy Theory: Finite spaces provide a discrete setting for studying homotopy theory. For example, the homotopy type of a finite space can be determined by its associated polyhedron, leading to insights into the classification of spaces.
