Ricci flow and positive curvature
Anusha Krishnan
University of Muenster. Abstract The Ricci flow is a geometric PDE for evolving with time a Riemannian
metric on a given manifold. The Ricci flow is heuristically like a
heat equation for the metric, and its regularizing properties have
been used with great success in solving problems in geometry and
topology.
In this talk I will discuss joint work with R. Bettiol showing that
positive curvature is not preserved under the Ricci flow on closed
manifolds in dimension 4. This is in contrast to dimension 3, where
the preservation of positive curvature under the flow is a crucial
step in Hamilton???s theorem that a simply-connected closed 3-manifold
with positive Ricci curvature is diffeomorphic to the 3-sphere. Our
examples come from metrics on $S^4$ and $\mathbb{C}P^2$ that have a
large group of isometries.
I will discuss background on positive curvature and the Ricci flow,
and explain how symmetry enters the proof.
