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…
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…
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…
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…
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…
Structural sign herdability of linear time-invariant systems:theory and design for arbitrary network structures
Pradeep M, Twinkle Tripathy
The objective of this paper is to investigate graph-theoretic conditions for structural herdability of an LTI system. In particular, we are interested in the structural sign (SS) h…
