Algebra Seminar

Tight objects in Lie Theory

Robert Bédard (UQAM)

Friday March 2, 12:05--12:55pm, Carslaw 175


G.Lusztig constructed a basis of the negative part of a quantized enveloping algebra. This canonical basis has nice properties. Tight monomials are the simplest elements of this basis. I will first describe the notion of tight monomials in the context of quantized enveloping algebras. Then there is a similar situation in the context of perverse sheaves arising from graded Lie algebras that could be seen as a generalization. This will also be considered in the talk.


After the seminar we will take the speaker to lunch.

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