Passcode: AMSS2022Organizer: Quoc-Hung Nguyen , Academy of Mathematics and Systems Science,
Chinese Academy of Sciences, Beijing.
The Seminar's purpose is to promote and influence more cooperation, understanding, and collaboration among scientists working in Partial Differential Equations.
Due to the coronavirus pandemic and in a time of social distancing, PDE Seminar via Zoom aims to provide such a venue for the PDE community, and keep as many researchers as possible stay connected.
Upcoming Talks

Speaker: Susanna Terracini, Università di Torino
Title: Free boundaries in segregation problems

Speaker: Hongjie Dong, Brown University
Title: Sobolev estimates for fractional PDEs
Abstract: I will discuss some recent results on Sobolev estimates for fractional elliptic and parabolic equations with or without weights. We considered equations with time fractional derivatives of the Caputo type, or with nonlocal derivatives in the space variables, or both. This is based on joint work with Doyoon Kim (Korea University) and Yanze Liu (Brown).

Title: The two-phase quasi-stationary Stokes flow by capillarity in the plane
Abstract: We discuss a two-phase moving boundary problem that describes the two-dimensional quasistationary Stokes flow of two fluids with different densities and viscosities that occupy the entire plane in the regime where surface tension effects are taken into account at the interface that separates the fluids. In this setting the classical methods of potential theory can be used to transform the model into a nonlinear and nonlocal evolution problem for the function that parameterizes the interface between the fluids, the nonlinearities being expressed by singular integral operators. This problem is of parabolic type, well-posed in all Sobolev spaces up to critical regularity, and it features some parabolic smoothing properties. Joint work with Georg Prokert.
