Ricci flow on modified Riemann extensions [PDF]

open access: yesarXiv, 2015
We study the properties of Modified Riemann extensions evolving under Ricci flow. We obtain the necessary and sufficient condition for modified Riemann extension under Ricci flow to stay as modified Riemann extension. We also discuss the properties of the curvature tensors under Ricci flow.

Almost Hermitian Ricci flow [PDF]

open access: yesarXiv, 2020
We introduce a new curvature flow which matches with the Ricci flow on metrics and preserves the almost Hermitian condition. This enables us to use Ricci flow to study almost Hermitian manifolds.

Designing, Developing and Examining the Effectiveness of a Machine Learning–Based Mobile Recommendation System for Parents' Digital Parenting Skills

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT It is of paramount importance that children are equipped with the requisite digital parenting skills to protect them from the risks and threats that they may encounter in the digital environment while also enabling them to seize the opportunities that the digital realm presents.

Swampland, gradient flow and infinite distance

open access: yesJournal of High Energy Physics, 2020
In the first part of this paper we will work out a close and so far not yet noticed correspondence between the swampland approach in quantum gravity and geometric flow equations in general relativity, most notably the Ricci flow.

Ricci Flow on 3-dimensional Lie groups and 4-dimensional Ricci-flat manifolds [PDF]

open access: yesarXiv, 2009
We study relation of the Ricci Flow on 3-dimensional Lie groups and 4-dimensional Ricci-flat manifolds. In particular, we construct Ricci-flat cohomogeneity one metrics with respect to 3-dimensional Lie groups.

A Bibliometric Analysis of Four Decades of Shareholder Activism Research

open access: yesCorporate Governance: An International Review, EarlyView.
ABSTRACT Research Questions/Issue In this bibliometric review of shareholder activism literature spanning 1983–2021, we pursue two objectives. Firstly, we investigate the degree of interdisciplinarity in the field, and second, we scrutinize publication trends, foundational knowledge, core topics, and emerging thematic trends, exploring the trajectory ...

Eigenvalues of the Laplacian under the Ricci flow [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2007
We derive, under a technical assumption, the first variation formula for the eigenvalues of the Laplacian on a closed manifold evolving by the Ricci flow and give some applications.

The Ricci flow and the early universe

open access: yesAnnals 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 ...
