G. Courtois - Compactness and Finiteness Results for Gromov-Hyperbolic Spaces 4
This is a series of lectures on Bishop--Gromov's type inequalities adapted to metric spaces. We consider the case of Gromov-hyperbolic spaces and draw consequences of these inequalities such as

P. Castillon - CAT(k)-spaces 4
The purpose of this course is to introduce the synthetic treatment of sectional curvature upper-bound on metric spaces. The basic idea of A.D. Alexandrov was to characterize the curvature bounds
