Algebra Seminar

The geometry of special pieces

Pramod Achar

23th February, 12:05-12:55pm, Carslaw 373


Let G be a reductive algebraic group over an algebraically closed field. The geometry of the unipotent variety in G plays a central role in its representation theory, and in this talk, I'll discuss a small corner of this vast topic: a set of conjectures by Lusztig on what certain subvarieties of the unipotent variety, called "special pieces", should look like. I'll also try to say something about potential applications in the dreamy, ethereal world of "spetses". This is joint work with D. Sage.

After the seminar we will take the speaker to lunch.

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