Ricci Curvature and the Stream of Thought

Psychological Methods
Abstract This paper investigates the dynamics of semantic associations by exploring the interplay between continuity and direction, in a geometric semantic space. While acknowledging the role of continuity in guiding associations, our work introduces the notion of Direction as a crucial factor influencing transitions.

On the blow-up of four-dimensional Ricci flow singularities [PDF]

, 2013
textIn 2002, Feldman, Ilmanen, and Knopf constructed the first example of a non-trivial (i.e. non-constant curvature) complete non-compact shrinking soliton, and conjectured that it models a Ricci flow singularity forming on a closed four-manifold.

Some New results in Ricci Curvature

Irish Mathematical Society Bulletin, 1996
The main results of the author's Ph. D. thesis [University of Notre Dame (1995)] are announced: an improvement of a surgery theorem for positive Ricci curvature originally given by \textit{J.-P. Sha} and \textit{D.-G. Yang} [J. Differ. Geom. 33, No.

Ricci solitons and curvature inheritance on Robinson-Trautman spacetimes

, 2023
The purpose of the article is to investigate the existence of Ricci solitons and the nature of curvature inheritance as well as collineations on the Robinson-Trautman (briefly, RT) spacetime.

Ricci curvature, graphs and Coxeter groups

, 2020
In the last decades there has been a research trend in combinatorics to translate notions of Riemannian geometry in graph theory (see for example [12], [7], [34],[23],[13],[5],[4],[3],[32],[11],[31],[29],[8],[9],[33],[19] ). In [41] a definition of Ricci

Optimization of Soliton Structures Using Lifting Theory on Tangent Bundles of Statistical Kenmotsu Manifolds

Journal of Mathematics
This paper investigates the optimization of soliton structures on tangent bundles of statistical Kenmotsu manifolds through lifting theory. By constructing lifted statistical Kenmotsu structures using semisymmetric metric and nonmetric connections, we ...

Isoperimetric profile function comparisons with Integral Ricci curvature bounds

We prove comparison results for the Isoperimetric profile function in the setting of manifolds with integral bounds on the Ricci curvature. We extend previous work of Ni and Wang and Bayle and Rosales under the usual pointwise bounds for the Ricci ...
