2018 Intercity Geometry Seminar

The spring 2018 Intercity Geometry Seminar will be held around Mirror Symmetry and moduli spaces of Higgs bundles. We will be following a recent preprint of Grochenig, Wyss and Ziegler in which they prove a conjecture of Hausel and Thaddeus on the Hodge numbers of these moduli spaces. Announcements will be sent out via the am-l mailing list. We will be posting an outline of the seminar below, which will be updated and adjusted as we progress. If you want to volunteer a presentation, please contact David Holmes, Arne Smeets or Chris Lazda.
