Seminar on Geometric Analysis and Its Applications: Rational ellipticity of Riemannian manifolds

Speaker: Xiaoyang Chen (Tongji University)

Abstract: It was conjectured by Bott-Grove-Halperin that a compact simply connected Riemannian manifold with nonnegative sectional curvature is rationally elliptic, i.e., it has finite dimensional rational homotopy groups. We will discuss some recent progress on this conjecture.
