Title: Ricci curvature, the length of a shortest periodic geodesic and quantitative Morse theory on loop spaces

Abstract: I am planning to present the following result of
mine: Let Mn be a closed Riemannian manifold of dimension n and Ric ≥(n-1).
Then the length of a shortest periodic geodesic can be at most 8πn.

The technique involves quantitative Morse theory on loop spaces. We will
discuss some related results in geometry of loop spaces on Riemannian
manifolds.
