Small-world properties of the Indian railway network.
TL;DR: Rigorous analysis of the existing data shows that the Indian railway network displays small-world properties and several other quantities associated with this network are defined and estimated.

Sociophysics: An Introduction
TL;DR: In this article, the authors present basic features of social systems and modelling, including the following: 1) Basic features of the social system and modelling; 2) Opinion formation in a society; 3) Social choices and popularity; 4) Crowd avoiding dynamical phenomena; and 5) Social phenomena on complex networks.
Journal ArticleDOI
Disorder induced phase transition in kinetic models of opinion dynamics
TL;DR: Results from exact calculation of a discrete version and numerical simulations of the continuous version of the model indicate the existence of a universal continuous phase transition at p=pc below which a consensus is reached.
Journal ArticleDOI
Aging in citation networks
TL;DR: This work studies actual citation networks to find out the distribution T(t) of t, the time interval between the published and the cited paper, and finds a universal behaviour: T(T)∼t-0.9 for t⩽tc and T( t)∽t-2 for t>tc.

Covid-19 spread: Reproduction of data and prediction using a SIR model on Euclidean network
TL;DR: It is reported here that the SIR model on the Eucledean network can reproduce with a high accuracy the data for China for given parameter values, and can also predict when the epidemic, at least locally, can be expected to be over.
