Title:   Some combinatorics of affine sl(n) crystals.

Date:    *** Tuesday ***, 9 June 2009
Time:    12:00 noon
Venue:   RC-4082, Red-Centre, UNSW

Abstract:

The crystals of the irreducible highest weight
representations for affine sl(n) have been studied
extensively, and have various combinatorial models.
We will discuss a few of these models, their structure,
and how they are related. In particular, we will discuss
a recent model where the vertices are indexed by
cylindric plane partitions. In some cases this model
leads to particularly clean statements.
