An algebraic framework of weighted directed graphs [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We show that an algebraic formulation of weighted directed graphs leads to introducing a k‐vector space equipped with two coproducts Δ and verifying the so‐called coassociativity breaking equation . Such a space is called an L‐coalgebra. Explicit examples of such spaces are constructed and links between graph theory and coassociative coalgebras are ...

A distance metric between directed weighted graphs [PDF]

open access: yes52nd IEEE Conference on Decision and Control, 2013
Directed weighted graphs are increasingly used to model complex systems and interactions, such as networks of interconnected physical or biological subsystems. The analysis of these graphs often requires some form of dissimilarity, or distance measure to compare graphs.

Edge-weighted anonymity for directed network graph

open access: yesIntelligent and Converged Networks
In social networks, weighted graph anonymity is gaining more and more attention. But fan-following graphs like Twitter’s are not protected by anonymity.

Adjasankey: Visualization of Huge Hierarchical Weighted and Directed Graphs [PDF]

open access: yes2015 19th International Conference on Information Visualisation, 2015
Visualization of hierarchical weighted and directed graphs are usually done with node-link or adjacency matrix diagrams. However, these representations suffer from various drawbacks: low readability in a context of Big Data, high number of edge crossings, difficulty to efficiently represent the weighting.

Cheeger Inequalities for General Edge-Weighted Directed Graphs [PDF]

open access: yesLecture Notes in Computer Science, 2015
We consider Cheeger Inequalities for general edge-weighted directed graphs. Previously the directed case was considered by Chung for a probability transition matrix corresponding to a strongly connected graph with weights induced by a stationary distribution.

Weighted Consensus Problem for Multiagent Systems with Edge- and Node-Weighted Directed Graphs

open access: yesComplexity, 2019
In this paper, the concept of consensus is generalized to weighted consensus, by which the conventional consensus, the bipartite consensus, and the cluster consensus problems can be unified in the proposed weighted consensus frame. The dynamics of agents

Unit dual quaternion directed graphs, formation control and general weighted directed graphs

open access: yesDiscrete Applied Mathematics
We study the multi-agent formation control problem in a directed graph. The relative configurations are expressed by unit dual quaternions (UDQs). We call such a weighted directed graph a unit dual quaternion directed graph (UDQDG). We show that a desired relative configuration scheme is reasonable or balanced in a UDQDG if and only if the dual ...

Coordination Games on Weighted Directed Graphs [PDF]

open access: yesMathematics of Operations Research, 2022
We study strategic games on weighted directed graphs, where each player’s payoff is defined as the sum of the weights on the edges from players who chose the same strategy, augmented by a fixed nonnegative integer bonus for picking a given strategy. These games capture the idea of coordination in the absence of globally common strategies.
