WebSo now I have to show that $(\bigcap_{n=1}^\infty V_n)\cap\bigcap_{q\in\mathbb Q}(\mathbb R\setminus\{q\})$ is dense, but that's a countable intersection of dense open subsets of $\mathbb R$, so by the Baire category theorem . . . The Baire category theorem gives sufficient conditions for a topological space to be a Baire space. WebThis is a basic result in the theory of group actions, as the orbit-stabilizer theorem. According to Wikipedia, Burnside attributed this lemma to an article of Frobenius of 1887, in his book "On the theory of groups of finite order", published in 1897.
