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.
