Prüfer surface

An example of a two-dimensional real-analytic manifold (cf. also Analytic manifold) not having a countable basis of open sets.

It was introduced in a paper of T. Radó [1]. There is a generalization of the Prüfer surface to any even dimension (cf. [2]).

However, every Riemann surface has a countable basis of open sets (Radó's theorem).
