It has been claimed and disputed that World War II has been followed by a `long peace', an unprecedented decline of war. We conduct a full changepoint analysis of well-documented, publicly-available battle deaths datasets, using new techniques that e

We use an established semi-mechanistic Bayesian hierarchical model of the COVID-19 pandemic [1], driven by European mortality data, to estimate the prevalence of immunity. We allow the infection-fatality ratio (IFR) to vary, adapt the model’s prior

The article of record as published may be found at http://dx.doi.org/10.1287/opre.2018.1718 We extend classical force-on-force combat models to study the attrition dynamics of three-way and multilateral war. We introduce a new multilateral combat mod

Historical outcomes were at one time only possibilities – but how do we distinguish probable real events from improbable ones? Niall MacKay, Chris Price and A. Jamie Wood use a naval battle of the First World War to explain how Bayesian thinking he

We present a general method of folding an integrable spin chain, defined on a line, to obtain an integrable open spin chain, defined on a half-line. We illustrate our method through two fundamental models with sl(2) Lie algebra symmetry: the Heisenbe

Simple dynamical systems, in the spirit of Richardson’s arms race, can be used to investigate the core dynamics of various models of insurgent and multilateral war. This chapter describes two such models. The first combines Richardson’s two-natio

The article of record as published may be found at https://doi.org/10.1287/opre.2020.2022 Existing Lanchester combat models focus on two force parameters: numbers (force size) and per-capita effectiveness (attrition rate). While these two parameters

We describe a new phenomenon in models of coalescence and fragmentation, that of gel-shatter cycles. These are dynamical, unforced, stochastic cycles in which slow, approximately deterministic coalescence up to and beyond gelation is followed by abru

We re-analyse the 1916 Battle of Jutland (German: Skagerrak), the major naval engagement of the First World War, in the light of the understanding of dreadnought fleet tactics developed over the decade leading up to it. In particular, we consider the

Lanchester's "Laws of Combat" are mathematical principles that have long been used to model military conflict. More recently, they have been applied to conflict among animals, including ants, birds, lions, and chimpanzees. Lanchester's Linear Law sta
