Title: Some Riemannian geometric properties and Weyl structures

Abstract: In this talk, we discuss a tie between Riemannian and semi-Riemannian geometry. More specifically, we will relate several classical Riemannian geometric properties, such as integral Reilly formula, local Bochner technique, and its applications including inequalities, geometric bounds, rigidity results etc. to the well-known Weyl conformal and projective structures from general relativity.
