# GRADuate International School in COmbinatorics

Here you can find the lecture notes. If you find any typos or mistakes, please let me know. If you don’t feel very comfortable with representation theory and have found this part of the course too sketchy (it definitely was very sketchy), you might want to look into slightly more detailed notes on this topic:

Here I give a quick (but more detailed) crash course on the representation theory of finite groups,

Here you can find some details on the representation theory of the symmetric group.

Here are the slides explaining the RSK algorithm. Finally,

the exercises are almost ready (warning: this file might constantly change).
