DESCRIPTION:Speaker: Nan Wu\, University of Texas at Dallas\n\n\n\nTitle: L
ENGTH OF A SHORTEST CLOSED GEODESIC IN MANIFOLDS OF DIMENSION FOUR\n\nAbstr
act: In this talk\, we show that for any closed 4-dimensional simply-connec
ted Riemannian manifold M with Ricci curvature |Ric| <= 3k\, volume vol(M)
> v > 0 and diameter diam(M) <= D\, the length of a shortest closed geodesi
c on M is bounded by a function F(k\,v\,D). The proof of this result is bas
ed on the diffeomorphism finiteness theorem for the manifolds satisfying ab
ove conditions proved by J. Cheeger and A. Naber. This talk is based on the
joint work with Zhifei Zhu.
