1-2-3 Seminar: From manifolds, schemes and group actions

In this talk, I am going to introduce and give intuitions about many geometric objects via examples. We are going to start with ideas in manifolds, step towards schemes and algebraic spaces, and finally talk about stacks and "gerbes" via the many variations of the example of a bug eyed line.
