In mathematics, Erdős space is a topological space named after Paul Erdős, who described it in 1940. Erdős space is defined as a subspace E ⊂ ℓ 2 of the Hilbert space of square summable sequences, consisting of the sequences whose elements are all rational numbers. Erdős space is a totally disconnected, one-dimensional topological space. The space E is homeomorphic to E × E in the product topology. If the set of all homeomorphisms of the Euclidean space R n that leave invariant the set Q n of ra
