Comparison Theory of Distance Spheres along Geodesics
Documenta mathematica, Tome 25 (2020), pp. 2241-2302
Estimates for the principal curvature of distance spheres in Riemannian manifolds with sectional curvature bounded from below are well known. The same holds for the mean curvature of distance spheres in Riemannian manifolds with Ricci curvature bounded from below.
