Mathematics Lecture Notes

The University of Sydney's Bob Howlett maintains a web page with freely available lecture notes on several topics of mathematical interest, including number theory, galois theory and the theory of group representations. While we're talking about group representations, Cambridge's Lek-Heng Lim also has a web page up for the Part IIB Mathematical Tripos, covering - yes, you guessed it - representation theory. By the way, does anyone find it a tad bit strange that a page on lectures for Cambridge students is actually being hosted on a Stanford server?
