S.Duzhin COMBINATORICS OF SYMMETRIC GROUPS Lecture 4: Representations of the symmetric group From the combinatorial point of view, the main theorem of the representation theory of symmetric groups claims the isomorphism of two infinite graphs: the Young graph, built out of Young diagrams, and the Frobenius graph that comes from irreducible representations of the symmetric groups. ... The vertices of the Young graph Y are Young diagrams. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
