Mathematical models are increasingly being adapted to model criminal behaviour and may
be used to support traditional crime prevention methods. This review focuses on recent …

Drug trafficking and money laundering are nation destroyers which need rapid solution to
the mayhem because the menace has ruined livelihoods and fostered vices. For this reason …

A nonlinear crime model is generalized by introducing self-and cross-diffusion terms. The
effect of diffusion on the stability of non-negative constant steady states is applied. In …

In this present paper, the principles of optimal control theory is applied to a non-linear
mathematical model for the population dynamics of criminal gangs with variability in the sub …

This study explores the dynamics of crime and substance abuse within a population by
developing a novel mathematical model that integrates social interactions, rehabilitation …

This present paper considers the dynamics of two criminal gangs in a criminally active
population. In our deterministic approach, we present the gang rivalry model to measure the …

The emerging threat of criminal gangs in society has severe consequences on the socio-
economic well-being of individuals. To examine the impact of morally upright individuals and …

COVID-19 has been a significant threat to many countries worldwide. COVID-19 remains a
threat even in the presence of vaccination. The study formulates and analyzes a non-linear …

Black pod disease is a major threat to cocoa production worldwide. A mathematical model
for the spread of cacao black pod disease is presented in this article. The model takes into …

This paper presents an analysis and numerical simulation of financial crime population
dynamics using fractional order calculus and Newton's polynomial. The dynamics of …
