Bounded Ricci curvature and positive scalar curvature under Ricci flow [PDF]

open access: yesPacific Journal of Mathematics, 2023
The authors consider a compact smooth Riemannian manifold \((M,g)\) without boundary, and its Ricci flow, which is a smooth family of metrics \( (g(t))_{t\geq 0}\) satisfying \(\partial _{t}g(t)=-2\mathrm{Ric}(g(t))\), where \(\mathrm{Ric}(g(t))\) denotes the Ricci curvature tensor of \(g(t)\), with the initial condition \(g(0)=g\).

On the projective Ricci curvature

open access: yesScience China Mathematics, 2020
The notion of the Ricci curvature is defined for sprays on a manifold. With a volume form on a manifold, every spray can be deformed to a projective spray. The Ricci curvature of a projective spray is called the projective Ricci curvature. In this paper,
