This seminar is about the singularity of PDEs in hydrodynamics and quantum mechanics, led by Prof. Huang's group. The relevant informations and sources(including recording videos and documents) will be updated in this post. Contents Our seminar proceed as follows: Ni will mainly introduce the recent works by Merle-Raphaël-Rodnianski-Szeftel, which worked out the Millennium problem in compressible version. Some related topics, like shock waves and other types of singularity, will also considered in our seminar. And Meng and Gu will lecture basic theory of elliptic equations. See references at the end. Schedule and sources We schedule on every Friday, 2:00-5:30 pm, located at Siyuan building S615, AMSS, CAS. No. Schedule Topic Lecturer Notes Records Location 1 24.03.08 Singularity & Stability A.

This page is a archive of the following seminars led by Prof. Huang's group. We will update the relevant informations and upload sources(including recording videos and documents) in this post. Summary The main informations of the topics will be listed here. Please check the last section for the schedule and uploaded sources. Schauder theory of elliptic equations.
