    Zabrodsky Lecture 2: Cohomological Field Theories

    Lecturer: 

    Rahul Pandharipande (ETH Zurich)
    11:00am to 12:00pm

    Location: 

    Ross 70
    Cohomological Field Theories (CohFTs) were introduced to keep track of the classes on the moduli spaces of curves defined by Gromov-Witten theories and their cousins. I will define CohFTs (following Kontsevich-Manin), explain the classification in the semisimple case of Givental-Teleman, and discuss the application to Pixton's relations which appear in the first lecture.

    Zabrodsky Lecture 3: CohFT calculations

    Lecturer: 

    Rahul Pandharipande (ETH Zurich)
    2:00pm to 3:00pm

    Location: 

    Ross 70
    I will explain how calculations of various natural classes on the moduli of curves fit into the CohFT framework. These include calculations related to Hilbert schemes of points, Verlinde bundles, and, if time permits, double ramification (DR) cycles.
