How Much Do You Know About Alvis-curtis Duality?

10 Questions  Settings  Most of the theories that we use today in mathematics are most of the time very old. It is as if all has already been invented or deciphered when it comes to math. Well, Alvis Curtis has proven us wrong because in the 1990s he came up with a new and bright theory. It is described as a duality operation on the characters of a reductive group over a finite field. So, how much do you know about it? Take our quiz and find out.
