Navarro González, Juan A. Finite topological spaces. (English) Zbl 1167.55300 Extr. Math. 5, No. 1, 32-34 (1990). Summary: We show that the study of topological \(T_0\)-spaces with a finite number of points agrees essentially with the study of polyhedra, by means of the geometric realization of finite spaces. In this paper all topological spaces are assumed to be \(T_0\).
