Hyperbolic Ricci-Bourguignon-Harmonic Flow [PDF]
Mathematics 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.

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

On Weak Super Ricci Flow through Neckpinch
Analysis 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 ...

Dynamical (In)Stability of Ricci-flat ALE metrics along the Ricci flow [PDF]
Calculus of Variations and Partial Differential Equations, 2021 We study the stability and instability of ALE Ricci-flat metrics around which a Łojasiewicz inequality is satisfied for a variation of Perelman’s $$\lambda $$ λ functional adapted to the ALE situation and denoted $$\lambda _{{\text {ALE}}}$$ λ ALE . This

Algebraic uniqueness of Kähler–Ricci flow limits and optimal degenerations of Fano varieties [PDF]
Geometry & Topology, 2020 We prove that for any $\mathbb{Q}$-Fano variety $X$, the special $\mathbb{R}$-test configuration that minimizes the $H$-functional is unique and has a K-semistable $\mathbb{Q}$-Fano central fibre $(W, \xi)$.

The Ricci flow on a cylinder [PDF]
Revista Colombiana de Matemáticas, 2017 En este artículo estudiamos el flujo de Ricci en superficies homeomorfas al cilindro (esto es, el producto de un círculo con un intervalo compacto). Al respecto, demostramos teoremas de existencia para todo tiempo de las soluciones asumiendo cierta simetría, teoremas sobre comportamiento asintótico, y reportamos un fenómeno interesante: la convergencia

The ∗-Ricci Operator on Hopf Real Hypersurfaces in the Complex Quadric
Mathematics, 2022 We study the ∗-Ricci operator on Hopf real hypersurfaces in the complex quadric. We prove that for Hopf real hypersurfaces in the complex quadric, the ∗-Ricci tensor is symmetric if and only if the unit normal vector field is singular.

Rotational symmetry of ancient solutions to the Ricci flow in higher dimensions [PDF]
Geometry & Topology, 2020 We extend the second part of \cite{Bre18} on the uniqueness of ancient $\kappa$-solutions to higher dimensions. We show that for dimensions $n \geq 4$ every noncompact, nonflat, complete, ancient solution of the Ricci flow that is uniformly PIC and ...
