Columbia Mathematics Department Colloquium

"Recent progress on Riemannian

manifolds of positive curvature"


Richard Schoen


We will discuss the geometric problem of classification of compact Riemannian manifolds
 of positive sectional curvature. In particular, we will describe our recent classification of pointwise
 1/4-pinched manifolds. The work is joint with Simon Brendle andemploys the Ricci flow.
