Ricci Flow and Its Applications [PDF]
, 2014 This thesis introduces the Ricci Flow and Its applications. Ricci flow has demonstrated its great potential by solving various problems in many fields, which can be hardly handled by alternative methods so far.

Archaeometry, EarlyView.ABSTRACT The object of this study consists of an archaeometric investigation of Early medieval Forum Ware glazed ceramics found in the central archaeological area of Rome, a significant chronological and economic marker for 8th–11th centuries. Instrumental analysis included digital microscopy, ESEM‐EDS imaging, EDS spectral analysis, EMPA quantitative ...

British Journal of Developmental Psychology, EarlyView.This review found a general association between sleep and reading ability in children, though some sleep outcomes are more robustly associated with reading than others. The strongest links between sleep and reading are seen in behavioural sleep outcomes, including general sleep disturbances, insomnia symptoms, sleep‐disordered breathing, daytime ...

Geometric Classifications of Perfect Fluid Space-Time Admit Conformal Ricci-Bourguignon Solitons
Journal of MathematicsThis paper is dedicated to the study of the geometric composition of a perfect fluid space-time with a conformal Ricci-Bourguignon soliton, which is the extended version of the soliton to the Ricci-Bourguignon flow.

Charting cellular differentiation trajectories with Ricci flow
Nature CommunicationsComplex biological processes, such as cellular differentiation, require intricate rewiring of intra-cellular signalling networks. Previous characterisations revealed a raised network entropy underlies less differentiated and malignant cell states.

The Architecture of Consolidation: Nests of Corporate Control in the Agrochemical Network
Journal of Agrarian Change, EarlyView.ABSTRACT Research on agricultural consolidation tends to equate corporate control with the dominance of a few large firms. We take an alternative approach that examines control through the explosive growth of legally distinct firms that fragment accountability. Using a new global dataset of 6982 entities linked to BASF, Bayer, Corteva, Dow, DuPont, FMC,

Mathematische Zeitschrift, 2011 Let $g(t)$ with $t\in [0,T)$ be a complete solution to the Kaehler-Ricci flow: $\frac{d}{dt}g_{i\bar j}=-R_{i\bar j}$ where $T$ may be $\infty$. In this article, we show that the curvatures of $g(t)$ is uniformly bounded if the solution $g(t)$ is uniformly equivalet. This result is stronger than the main result in Šešum \cite{sesum} within the category

The Ricci flow and the early universe
Annals of Physics, 2023 A framework of quantum spacetime reference frame is proposed and reviewed, in which the quantum spacetime at the Gaussian approximation is deformed by the Ricci flow. At sufficient large scale, the Ricci flow not only smooths out local small irregularities making the universe a homogeneous and isotropic Friedmann-Robertson-Walker metric, but also ...
