Dear All, Welcome to Semester 2 of the MaPS seminar series!! The next MaPS talk will be this week - Thursday, 1 August, at 5-6 pm in Carslaw AGR, as well as online via Zoom. This time, we have Alex, who will give us an overview of Ricci Curvature Behavior for the Kahler Ricci Flow. Please join us afterward, in the level 7 tea room, for some light dinner and social time! ========================================================================= Speaker: Alexander Bednarek Title: Global Ricci Curvature Behavior for the Kahler Ricci Flow with Finite Time Singularities Abstract: We consider the Ricci flow in the setting of Kahler manifolds. The Ricci flow is a tool for deforming smooth manifolds with respect to their Ricci curvature in hopes of extracting a nice metric, whereas Kahler manifolds are smooth manifolds equipped with compatible Riemannian, complex, and symplectic structures. These properties enable the study of the Kahler-Ricci flow to be reduced to that of a complex Monge-Ampere type PDE. In the case that the existence time is necessarily finite, we show that under the existence of a map into complex projective space and a cohomology condition, we can find an L^4-like estimate on the Ricci curvature, which enables us to better understand the flow as it approaches its time of singularity. Location: Carslaw AGR 829 and Zoom (https://uni-sydney.zoom.us/j/5445386416) Date: 1 Aug 2024 (Thursday), 5-6 PM ========================================================================= Thank you, and have a nice day!
