Title: On Nearly Schur-Type Theorems

Abstract: It is well-known that if the principal curvatures of
a surface in the Euclidean space depends on the base point only
(i.e. umbilic), then it has constant curvature. Another classical
result of Schur states that if the Ricci curvature of a Riemannian
manifold depends on the base point only, then its scalar curvature
is constant. I will give a unified viewpoint for these types of
results and give a quantitative version of these results for
closed Riemannian manifolds.
