Finite Homogeneous Spaces

Abstract

The authors prove that on a set with \(n>0\) elements there are up to homeomorphism \(\tau(n)\) homogeneous topologies. Here \(\tau(n)\) is the number of positive divisors of \(n\). They also prove that if \(X\) is finite and \(\tau\) is a connected homogeneous topology on \(X\) then \(\tau = \{\emptyset,X\}\). Moreover, if \(| X| =p\), where \(p\) is prime, then the only homogeneous disconnected topology on \(X\) is the discrete one.

Keywords

Topological characterizations of particular spaces, homogeneous space, Topological spaces and generalizations (closure spaces, etc.), finite topology
