Dear friends and colleagues, on Friday, 24 May 2024, at 5 pm is Ms Jingjing Ma (visiting PhD student from Shaanxi Normal University, China) giving a talk on her current research in our "working seminar in Analysis and PDEs". This presentation is organsided via a Zoom meeting: https://uni-sydney.zoom.us/j/88138974950 Meeting-ID: 881 3897 4950 Title: Nazaret’s proof of the sharp constant in a trace-Sobolev inequality Abstract: In this presentation, we will see the fine tools of optimal transportation in order to derive the sharp constant in the classical trace Sobolev inequality. I will outline all details of the proof. Thus, the talk is proceeding slowly but in all details.
