RICCI LOWER BOUND FOR KÄHLER–RICCI FLOW
View through CrossRef
We provide general discussion on the lower bound of Ricci curvature along Kähler–Ricci flows over closed manifolds. The main result is the non-existence of Ricci lower bound for flows with finite time singularities and non-collapsed global volume. As an application, we give examples showing that positivity of Ricci curvature would not be preserved by Ricci flow in general.
Title: RICCI LOWER BOUND FOR KÄHLER–RICCI FLOW
Description:
We provide general discussion on the lower bound of Ricci curvature along Kähler–Ricci flows over closed manifolds.
The main result is the non-existence of Ricci lower bound for flows with finite time singularities and non-collapsed global volume.
As an application, we give examples showing that positivity of Ricci curvature would not be preserved by Ricci flow in general.
