I was thinking about something yesterday and I couldn't quite figure it out. It's about the question if an atlas is a countable set. Because we know that every manifold is second countable, so it has a countable basis. But does every element of the basis fit inside a chart domain? If that's the case then the atlas is countable. But I'm not sure that's the case :)(adsbygoogle = window.adsbygoogle || []).push({});
