Broadly, the subject of our workshop is “groups and geometry”. A number of rich branches of mathematics lie at the intersection of these two large areas. More specifically, our main themes of interest are: geometric representation theory, group actions on manifolds and varieties, and combinatorial aspects of geometry and representation theory.

We plan on holding a workshop with four to five talks per day.Currently the draft schedule is for three talks on Friday afternoon and a full day on Saturday with five talks. We will invite speakers and participants from different Ontario universities and other regional institutions. There will be talks by faculty, post-docs, and senior graduate students, with emphasis on a high level of mathematical and communicative quality.
