Strictly nef subsheaves in tangent bundle
Speaker: Jie Liu (Chinese Academy of Sciences)

Time: 14h00, Friday, September 25, 2020

Abstract: Since the seminal works of Mori and Siu-Yau on the solutions to Hartshorne conjecture and Frankel conjecture, it becomes apparent that the positivity of the tangent bundle of a complex projective manifold carries important geometric information. In this talk, we will discuss the structure of projective manifolds whose tangent bundle contains a locally free strictly nef subsheaf and present a new characterisation of projective spaces. This is a joint work with Wenhao Ou (AMSS) and Xiaokui Yang (YMSC).
