Detecting network anomalies using Forman–Ricci curvature and a case study for human brain networks [PDF]

open access: yesScientific Reports, 2021
We analyze networks of functional correlations between brain regions to identify changes in their structure caused by Attention Deficit Hyperactivity Disorder (adhd).

Non-local interaction in discrete Ricci curvature-induced biological aggregation [PDF]

open access: yesRoyal Society Open Science
We investigate the collective dynamics of multi-agent systems in two- and three-dimensional environments generated by minimizing discrete Ricci curvature with local and non-local interaction neighbourhoods.

On $m$-th root metrics of isotropic projective Ricci curvature [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2023
The Ricci curvature is introduced by spray on $M^n$. Sprays are deformed to projective sprays with a volume form $dV$ on $M^n$. The projective Ricci curvature is defined as the expression of Ricci curvature with sprays.

Weighted Ricci curvature in Riemann-Finsler geometry [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
Ricci curvature is one of the important geometric quantities in Riemann-Finsler geometry. Together with the $S$-curvature, one can define a weighted Ricci curvature for a pair of Finsler metric and a volume form on a manifold.

Discrete Ricci curvatures capture age-related changes in human brain functional connectivity networks

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionGeometry-inspired notions of discrete Ricci curvature have been successfully used as markers of disrupted brain connectivity in neuropsychiatric disorders, but their ability to characterize age-related changes in functional connectivity is ...
