CU Algebraic Lie Theory Seminar

CU Algebraic Lie Theory Seminar

The seminar is jointly organized by Richard Green and Nat Thiem. For more information, please contact one of us.

This seminar covers a wide range of topics in Lie theory including (but not limited to) groups of Lie type, Lie algebras, Coxeter groups and their Hecke algebras, algebraic groups, and quantum groups, with emphasis on combinatorial and representation theoretic properties. Further information about upcoming seminars and people in the math department can be found at the CU Math Department Home Page.

Time: Tuesday, 2pm (talks are usually 50 minutes)
Location: Math 220
