    Geometry, Algebra and Topology Seminar

    Speaker: Chengyong Du, Sichuan Normal University

    Title: Elementary differential topology of orbifold groupoid

    Abstract:We consider elementary differential topology of orbifold groupoid (orbi-groupoid), such as the the concept of sub-orbi-groupoid, orbi-bundles, transversality of orbifold maps, Riemannian metric, tubular neighborhood of sub-orbi-groupoids. These properties are very necessary and useful for studying symplectic orbi-groupoids and their Gomov-Witten theories.

    Time:   3:30pm--5:30pm Tuesday, Dec 15, 2015

    Place:  X2415 Xipu campus at SWJTU
