• Fundamental forms and infinitesimal symmetries of projective varieties

    B236-1 IBS, Korea, Republic of
    Complex Geometry Seminar

        Speaker Qifeng Li Shandong University The fundamental form is a basic object for manifolds and varieties. In this talk, we will give a bound on the dimension of the linear automorphism group of a projective variety $Z \subset \mathbb{P} V$ in terms of its fundamental forms at a general point. Moreover, we will …

  • On isotrivial cone structures of highest weight type

    B236-1 IBS, Korea, Republic of
    Complex Geometry Seminar

        Speaker Yingqi Liu IBS CCG Hwang and Li introduced cone structures with characteristic conic connections, partially generalizing VMRT structures on uniruled projective manifolds. For isotrivial cone structures with fiber Z, they established a projective-geometric criterion on Z ensuring the existence of torsion-free connections on the associated G-structures. In this talk, I will describe …
