Sphere Theorems for <i>σ<sub>k</sub></i>-Einstein Manifolds

A problem that geometers have always been concerned with is when a closed manifold is isometric to a round sphere. A classical result shows that a closed locally conformally flat Einstein manifold is always isometric to a quotient of a round sphere. In this note, we provide the definitions of <in...
