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…
Structural Sign Herdability in Temporal Networks: A Sufficient Condition via -Graphs
Pradeep M, Twinkle Tripathy
In this letter, we study the herdability of temporally switching directed networks. A temporal network is modeled as a switched system with a fixed switching sequence, which impose…
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…
Structural Sign Herdability in Temporally Switching Networks with Fixed Topology
Pradeep M, Twinkle Tripathy
This paper investigates structural herdability in a special class of temporally switching networks with fixed topology. We show that when the underlying digraph remains unchanged a…
Steering Opinion Dynamics in Signed Time-Varying Networks via External Control Input
Swati Priya, Twinkle Tripathy
This paper studies targeted opinion formation in multi-agent systems evolving over signed, time-varying directed graphs. The dynamics of each agent's state follow a Laplacian-based…
