Connecting Hodge and Sakaguchi-Kuramoto: a mathematical framework for coupled oscillators on simplicial complexes

open access: yesCommunications Physics, 2021
We formulate a general Kuramoto model on weighted simplicial complexes where phases oscillators are supported on simplices of any order $k$. Crucially, we introduce linear and non-linear frustration terms that are independent of the orientation of the $k+1$ simplices, providing a natural generalization of the Sakaguchi-Kuramoto model.

MORPHOLOGICAL SPATIAL PATTERN ANALYSIS: OPEN SOURCE RELEASE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
The morphological segmentation of binary patterns provides an effective method for characterising spatial patterns with emphasis on connections between their parts as measured at varying analysis scales.

On a hierarchy of Booleanfunctions hard to compute in constant depth [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
Any attempt to find connections between mathematical properties and complexity has a strong relevance to the field of Complexity Theory. This is due to the lack of mathematical techniques to prove lower bounds for general models of computation. This

Elementary school students’ mathematical connection in problem-posing activities

open access: yesJurnal Elemen, 2022
The ability of mathematical connections possessed by students can be seen from the ability of students to compile math problems. This study aims to determine the type of mathematical connection made by elementary school students in problem-posing ...

Nonlinear Analysis of Rotational Springs to Model Semi-Rigid Frames

open access: yesEntropy, 2022
This paper explains the mathematical foundations of a method for modelling semi-rigid unions. The unions are modelled using rotational rather than linear springs.

Linear Datalog and Bounded Path Duality of Relational Structures [PDF]

open access: yesLogical Methods in Computer Science, 2005
In this paper we systematically investigate the connections between logics with a finite number of variables, structures of bounded pathwidth, and linear Datalog Programs.

Gintropy: Gini Index Based Generalization of Entropy

open access: yesEntropy, 2020
Entropy is being used in physics, mathematics, informatics and in related areas to describe equilibration, dissipation, maximal probability states and optimal compression of information.
