【学术报告】Criteria for type-IIb singularities of Kaehler-Ricci flow on minimal manifolds
报告人：张雅山（湖南大学）时 间：2023年8月3日14:30地 点：厦门大学海韵园实验楼105报告厅内容摘要:The curvature behavior is one of the most important aspects of the Kaehler-Ricci flow. In this talk we shall provide an overview on the curvature behavior of long-time solutions to the Kaehler-Ricci flow of collapsing structure, which intimately relate to the underlying complex structure. In particu...

【Colloquium】Hessian estimate for the sigma-2 equation in dimension four
报告人：袁域（美国华盛顿大学）时 间：2023年7月19日10:40地 点：厦门大学海韵园实验楼105报告厅内容摘要:We present joint work with Ravi Shankar on Hessian estimate and interior regularity for the sigma-2 equation in four dimensions. Our method also provides respectively a Hessian estimate for smooth solutions satisfying a dynamic semi-convexity condition in higher dimensions, and a new proof for ...

【名家讲堂】Collapsed manifolds with Ricci local bounded covering geometry
报告人：戎小春（美国罗格斯大学）时 间：2023年7月19日9:30地 点：厦门大学海韵园实验楼105报告厅内容摘要:A complete Riemannian n-manifold M is called epsilon-collapsed, if every unit ball in M has volume less than epsilon (while often a bound on `curvature' must be imposed to prevent a rescaling of metric). In 1978, Gromov classified `almost flat manifolds' (or the `maximally collapsed manifolds'...

【学术报告】Speed of explosion for continuous-state nonlinear branching processes with large jumps
报告人：周晓文（康考迪亚大学）时 间：2023年7月18日10:30地 点：厦门大学海韵园实验楼105报告厅内容摘要:Continuous-state branching processes (CSBPs) with nonlinear branching mechanism can be obtained from spectrally positive Lvy processes by generalized Lamperti time changes. These generalized CSBPs allow rich asymptotic behaviours such as extinction, explosion and coming down from infinity. The ...
