Algebra Seminar

Characters of affine Lie algebras and Hall-Littlewood functions


Friday 2nd November, 12:05--12:55pm, Carslaw 175


Ole Warnaar (University of Queensland)


Characters of affine Lie algebras and Hall-Littlewood functions


The celebrated Weyl-Kac character formula gives a closed-form expression for the characters of irreducible highest weight modules of affine Kac-Moody Lie algebras. One disadvantage of the Weyl-Kac formula is that it obscures the positivity of the characters. In this talk I will describe how the theory of Hall-Littlewood functions may be used to derive manifestly positive expressions for characters of affine Lie algebras.


After the seminar we will take the speaker to lunch.

See the Algebra Seminar web page for information about other seminars in the series.
