  • Index from a point

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Differential Geometry and Physics Seminar Speaker: Monica Jinwoo Kang, Texas A&M University Title: Index from a point Abstract: We argue that protected data of 4d N=2 SCFTs admits a purely algebro-geometric characterization. […]

  • On E7+1/2 gauge theory

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Differential Geometry and Physics Seminar Speaker: Yinan Wang, Peking University Title: On E7+1/2 gauge theory Abstract: We propose that an exotic gauge theory based on the intermediate Lie algebra E7+1/2 naturally appears […]
