While Prof. Schilling is in Germany, we have coordinated a reading group for those interested in crystal bases and crystal graphs for their research.
Regular participants include Tom Denton, Jeff Ferreira, Yvonne Kemper, Alex Lang, Katie O'Reilly, Travis Scrimshaw, and Rabhar Virk (rv).

Week 1: **Tom Denton** led an organizational meeting, and reprised an introduction to combinatorial crystal graphs that he gave in Kenya in December.

Week 2: **Katie O'Reilly** continued the introduction to combinatorial crystals, describing the tensor product rule and working through examples with the
group.

Week 3-4: **Jeff Ferreira** reviewed the representation theory of gl_n, and gave an overview of crystals arising from Demazure modules and their relation
to classical highest weight crystals.

Week 5: **Tom Denton** discussed the Stembridge local characterization of crystal bases for simply laced types.

Week 6-8: **Travis Scrimshaw and Tom Denton** presented the crystal structure on rigged configurations, including the bijection between rigged configuration and crystal elements, the algorithm for determining the crystal operators, and a few worked examples.

With one missed week and an organizational meeting, this filled out the whole term.
