Metaverse and Artificial Intelligence as Web 4.0: The Next Generation of the Internet

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This study utilizes systems thinking to explore and entwine an evolving metaverse scholarship to a relatively underexplored phenomenon of Web 4.0. We adopt a soft systems thinking framework to guide the interpretation of complex and evolving metaverse scholarship, using bibliometric mapping of 5587 publications sourced from Scopus.

Eigenvalue lower bounds and splitting for modified Ricci flow

Advanced Nonlinear Studies
We prove sharp lower bounds for eigenvalues of the drift Laplacian for a modified Ricci flow. The modified Ricci flow is a system of coupled equations for a metric and weighted volume that plays an important role in Ricci flow.

Stability of piecewise flat Ricci flow in three dimensions

Journal of Numerical Analysis and Approximation Theory
For a recently developed piecewise flat approximation of the Ricci flow, numerical instabilities are seen to arise for a particularly useful class of mesh-types.

Stability of ALE Ricci-Flat Manifolds Under Ricci Flow [PDF]

The Journal of Geometric Analysis, 2020
AbstractWe prove that if an ALE Ricci-flat manifold (M, g) is linearly stable and integrable, it is dynamically stable under Ricci flow, i.e. any Ricci flow starting close togexists for all time and converges modulo diffeomorphism to an ALE Ricci-flat metric close tog. By adapting Tian’s approach in the closed case, we show that integrability holds for

Enhancing Infrastructure Resilience in Service Utilities through Embedding Versatility in System Architecture

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Enhancing infrastructure resilience, a key component of transforming and sustainably developing service utilities, requires a transdisciplinary and systems engineering framework. Addressing vulnerabilities in system architecture offers opportunities for resilience improvements, thereby mitigating the environmental, social, and economic impacts

Topological Signals of Singularities in Ricci Flow

Axioms, 2017
We implement methods from computational homology to obtain a topological signal of singularity formation in a selection of geometries evolved numerically by Ricci flow.

Policy Evaluation for Climate Mitigations in the European Agricultural Sector—A Comparison of Policy Options at Micro and Macro Level

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...

On the Topological Classification of Four-Dimensional Steady Gradient Ricci Solitons with Nonnegative Sectional Curvature

Mathematics
In this paper, we study the topology of steady gradient Ricci solitons with nonnegative sectional curvature. We apply a characterization theorem for the fundamental group of a positively curved steady gradient Ricci soliton that admits a critical point ...

Organizational Culture and Financial Performance: A Machine Learning Approach*

Asia-Pacific Journal of Financial Studies, EarlyView.
Abstract This study explores the relationship between organizational culture and firm performance by applying a machine learning‐based text analysis to a large corpus of employee reviews. Inspired by an intuitive framework of Myers‐Briggs Type Indicator personality dimensions, we propose a novel representation of organizational culture using Korean ...

Generalized Ricci Flow

, 2020
This book gives an introduction to fundamental aspects of generalized Riemannian, complex, and K hler geometry. This leads to an extension of the classical Einstein-Hilbert action, which yields natural extensions of Einstein and Calabi-Yau structures as `canonical metrics' in generalized Riemannian and complex geometry.
