Concerning the topological interpretation of Mobius numbers
Today I asked in class whether one could extract more (topological) information from . I had the feeling that there had to be a connection between this and the Betti numbers of the order complex (those who have dealt with

Question concerning the term “connected.”
In the last lecture, Crista and I wondered about what the origin is of the term “connected” in Hopf algebras. Our guess was that it came from topology. Here is why I thought that the term might have originated from
