The SGA1 version of Riemann's Existence Theorem is about analytic spaces. How does one relate it to topological covering spaces?
@nfdc23 Why is that first sentence (of your first comment) correct? It seems like that's the whole point of the question.

@phys In more simple terms, it means that every simple module has a basis where the matrices of the action are rational (actually, you can make them integers), in particular, real.
