The Chern-Ricci flow [PDF]

open access: yesRendiconti Lincei, Matematica e Applicazioni, 2021
We give a survey on the Chern-Ricci flow, a parabolic flow of Hermitian metrics on complex manifolds. We emphasize open problems and new directions.

Symmetries of Ricci flows

open access: yesAdvances in Nonlinear Analysis, 2023
In the present work, we find the Lie point symmetries of the Ricci flow on an n-dimensional manifold, and we introduce a method in order to reutilize these symmetries to obtain the Lie point symmetries of particular metrics.

Weak scalar curvature lower bounds along Ricci flow [PDF]

open access: yesScience China Mathematics, 2021
In this paper, we study Ricci flow on compact manifolds with a continuous initial metric. It was known from Simon (2002) that the Ricci flow exists for a short time.

Uniqueness of compact ancient solutions to the higher-dimensional Ricci flow [PDF]

open access: yesJournal für die Reine und Angewandte Mathematik, 2021
In dimensions n ≥ 4 {n\geq 4} , an ancient κ-solution is a nonflat, complete, ancient solution of the Ricci flow that is uniformly PIC and weakly PIC2; has bounded curvature; and is κ-noncollapsed.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Small curvature concentration and Ricci flow smoothing [PDF]

open access: yesJournal of Functional Analysis, 2021
We show that a complete Ricci flow of bounded curvature which begins from a manifold with a Ricci lower bound, local entropy bound, and small local scale-invariant integral curvature control will have global point-wise curvature control at positive times

Hyperbolic Ricci-Bourguignon-Harmonic Flow [PDF]

open access: yesMathematics Interdisciplinary Research, 2022
In this paper, we consider hyperbolic Ricci-Bourguignon flow on a compact Riemannian manifold M coupled with the harmonic map flow between M and a fixed manifold N. At the first, we prove the unique short-time existence to solution of this system.

Parabolic Frequency Monotonicity on Ricci Flow and Ricci-Harmonic Flow with Bounded Curvatures [PDF]

open access: yesJournal of Geometric Analysis, 2022
In this paper, we study the monotonicity of parabolic frequency motivated by Baldauf and Kim (Parabolic frequency on Ricci flows. To appear in Int. Math. Res. Not., rnac128.

On Weak Super Ricci Flow through Neckpinch

open access: yesAnalysis and Geometry in Metric Spaces, 2021
In this article, we study the Ricci flow neckpinch in the context of metric measure spaces. We introduce the notion of a Ricci flow metric measure spacetime and of a weak (refined) super Ricci flow associated to convex cost functions (cost functions ...
