Title: Relaxation limits of compressible one-velocity bifluid systems
Jin Tan - Chinese University of Hong Kong
Consider a one-velocity Baer–Nunziato system with friction forces. I will first justify its pressure-relaxation limit toward a Kapila model in a uniform manner with respect to the time-relaxation parameters associated with the friction forces. Then, I will show that the diffusely rescaled solutions of the damped Kapila system converge to the solutions of the new two-phase porous media system as the remain time-relaxation parameter tends to zero. For each relaxation limit, rates of convergence will be discussed.

Title: The Yamabe problem for metrics of Sobolev regularity
Andoni Royo - University of Tübingen
The Yamabe problem is one of the central topics in geometric analysis, which lies in the intersection of differential geometry, non-linear PDE and general relativity. It consists of finding a conformal deformation from a given Riemannian manifold, into another one with constant scalar curvature. The problem turns out to be equivalent to finding positive solutions to a variational semi-linear elliptic PDE with critical non-linearity. In particular, standard variational techniques do not work, and analysis and geometry (even physics!) need to talk to each other in order to find a solution. In this talk, we will summarize the classical resolution to the Yamabe problem in 3 dimensions and present new results based on joint work with Rodrigo Avalos and Albachiara Cogo
