Influence Enhancement in Opinion Dynamics Using Edge Modification: A Kron Reduction-Based Approach
Aashi Shrinate, Aravind Seshadri, Twinkle Tripathy +3
With the emergence of online social networks as a primary platform for advertising and advocacy, enhancing a user's influence has become of significant interest. In this paper, we…
Topological Conditions for Echo Chamber Formation under the FJ model: A Cluster Consensus-based Approach
Aashi Shrinate, Twinkle Tripathy, Laxmidhar Behera
The Friedkin-Johnsen (FJ) model is a popular opinion dynamics model that explains the disagreement that can occur even among closely interacting individuals. Cluster consensus is a…
Topology-based Conditions for Multiconsensus under the Signed Friedkin-Johnsen Model
Aashi Shrinate, Tanmay Siddharth, Twinkle Tripathy
In this paper, we address the multiconsensus problem in networked systems, where agents are partitioned into disjoint subgroups and the states of agents within a subgroup are drive…
A Signed Friedkin-Johnsen Model for Arbitrary Network Topologies
Aashi Shrinate, Twinkle Tripathy
The paper presents an opposing rule-based signed Friedkin-Johnsen (SFJ) model for the evolution of opinions in arbitrary network topologies with signed interactions and stubborn ag…
Opinion Clustering under the Friedkin-Johnsen Model: Agreement in Disagreement
Aashi Shrinate, Twinkle Tripathy
The convergence of opinions in the Friedkin-Johnsen (FJ) framework is well studied, but the topological conditions leading to opinion clustering remain less explored. To bridge thi…
Leveraging Network Topology in a Two-way Competition for Influence in the Friedkin-Johnsen Model
Aashi Shrinate, Twinkle Tripathy
In this paper, we consider two stubborn agents who compete for `influence' over a strongly connected group of agents. This framework represents real-world contests, such as competi…
Towards influence centrality: where to not add an edge in the network?
Aashi Shrinate, Twinkle Tripathy
In this work, we consider a strongly connected group of individuals involved in decision-making. The opinions of the individuals evolve using the Friedkin-Johnsen (FJ) model. We co…
External Bias and Opinion Clustering in Cooperative Networks
Akshay Nagesh Kamthe, Vishnudatta Thota, Aashi Shrinate +1
In this work, we consider a group of n agents which interact with each other in a cooperative framework. A Laplacian-based model is proposed to govern the evolution of opinions in…
Absolute centrality in a signed Friedkin-Johnsen based model: a graphical characterisation of influence
Aashi Shrinate, Twinkle Tripathy
This paper studies the evolution of opinions governed by a Friedkin Johnsen (FJ) based model in arbitrary network structures with signed interactions. The agents contributing to th…
