SUMMARY:Fundamental forms and infinitesimal symmetries of projective varieties
DESCRIPTION:    Speaker\n\n\nQifeng Li\nShandong University\n\n\n\n\n\n\nThe 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 show that the bound is achieved precisely when $Z \subset \mathbb{P} V$ is projectively equivalent to an Euler-symmetric variety. The applications in the rigidity problem will also be discussed. This talk is based on a joint work with Jun-Muk Hwang.

SUMMARY:On isotrivial cone structures of highest weight type
DESCRIPTION:    Speaker\n\n\nYingqi Liu\nIBS CCG\n\n\n\n\n\n\nHwang 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.\nIn this talk\, I will describe a classification of rational homogeneous varieties Z satisfying their criterion and its application to VMRT structures\, generalizing results for adjoint varieties. I will explain how this problem naturally leads to the study of Gaussian maps.
