The Soliton-Ricci Flow with variable volume forms

open access: greenComplex Manifolds, 2016
We introduce a flow of Riemannian metrics and positive volume forms over compact oriented manifolds whose formal limit is a shrinking Ricci soliton. The case of a fixed volume form has been considered in our previouswork.We still call this new flow, the ...

Pluripotential Kähler–Ricci flows [PDF]

open access: greenGeometry & Topology, 2020
We develop a parabolic pluripotential theory on compact K{ }hler manifolds, defining and studying weak solutions to degenerate parabolic complex Monge-Amp{ }re equations. We provide a parabolic analogue of the celebrated Bedford-Taylor theory and apply it to the study of the K{ }hler-Ricci flow on varieties with log terminal singularities.

Non-local interaction in discrete Ricci curvature-induced biological aggregation [PDF]

open access: yesRoyal Society Open Science
We investigate the collective dynamics of multi-agent systems in two- and three-dimensional environments generated by minimizing discrete Ricci curvature with local and non-local interaction neighbourhoods.

Scalar Curvature, Entropy, and Generalized Ricci Flow [PDF]

open access: yesInternational mathematics research notices, 2022
We derive a family of weighted scalar curvature monotonicity formulas for generalized Ricci flow, involving an auxiliary dilaton field evolving by a certain reaction–diffusion equation motivated by renormalization group flow.

On finite time Type I singularities of the Kähler–Ricci flow on compact Kähler surfaces [PDF]

open access: yesJournal of the European Mathematical Society (Print), 2022
We show that the underlying complex manifold of a complete non-compact two-\linebreak dimensional shrinking gradient K\"ahler-Ricci soliton $(M,\,g,\,X)$ with soliton metric $g$ with bounded scalar curvature $\operatorname{R}_{g}$ whose soliton vector ...

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.

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.
