Diff. Geom, Math. Phys., PDE Seminar: Yannick Sire

A great amount of work has been dedicated in the last years to understand problems with integral diffusion for elliptic, parabolic or hyperbolic equations and systems. In this talk, I will describe a new Yamabe problem based on conformally covariant elliptic operators of fractional order. I will describe some new results on existence of metrics for the regular and singular problems.
