Abstract: In this talk, I will present a singular version of the Sphere Covering Inequality and its applications in the study of singular Liouville-type problems with super harmonic weights. In particular, new uniqueness results for solutions of the singular mean field equation both on spheres and on bounded domains will be discussed. This approach also gives a new self-contained proofs of previously known results, such as the uniqueness of spherical convex polytopes first established by Luo and Tian. Furthermore, I will also show new symmetry results for the spherical Onsager vortex equation.
