Graduate Two cones connected at their vertices do not form a manifold
The common vertex is a cut point of order 2, this means that if you take it away from the space, you end up with a disconnected space with 2 components.

Intro Math Books for Learning Proofs | Jonathan
I don't think it is essential to read a proof book in order to start doing math. If you're strugging with Apostol I doubt a proof book will help much, better to read another analysis book alongside Apostol or a naive set theory book such as the one by Halmos.- Cruz Martinez

I have a question: In the US, are you required by law to stop if a police officer asks you to stop so he can ask you questions (e.g. you're walking down the...- Cruz Martinez

Is intelligence determined by popular vote?
There you go reducing the thread to a single perspective. It's like saying "no-one understands you", it's truthfully 'the majority' and not 'no-one', but you are frustrated to become secure in your falsity.- Cruz Martinez
