Competitive epidemic networks with multiple survival-of-the-fittest outcomes

  title={Competitive epidemic networks with multiple survival-of-the-fittest outcomes},
  author={Mengbin Ye and Brian Anderson and Axel Janson and Sebin Gracy and Karl Henrik Johansson},
We use a deterministic model to study two competing viruses spreading over a two-layer network in the Susceptible–Infected–Susceptible (SIS) framework, and address a central problem of identifying the winning virus in a “survival-of-the-fittest” battle. Existing sufficient conditions ensure that the same virus always wins regardless of initial states. For networks with an arbitrary but finite number of nodes, there exists a necessary and sufficient condition that guarantees local exponential…

Competitive Epidemic Spreading Over Networks

In this letter, we consider an epidemic model for two competitive viruses spreading over a metapopulation network, termed the ‘bivirus model’ for convenience. The dynamics are described by a

Modeling and Analysis of a Coupled SIS Bi-Virus Model

The paper deals with the setting where two viruses (say virus 1 and virus 2) coexist in a population, and they are not necessarily mutually exclusive, in the sense that infection due to one virus

Convergence and Equilibria Analysis of a Networked Bivirus Epidemic Model

It is shown that it is possible for a bivirus network to have an unstable coexistence equilibrium and two locally stable boundary equilibria, and how to use monotone systems theory to generate conclusions on the ordering of stable and unstableEquilibria.

This dissertation aims to provide a history of web exceptionalism from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year in which descriptions of “Web 2.0” began to circulate.

Bi-virus Epidemics over Large-scale Networks: Emergent Dynamics and Qualitative Analysis

This Thesis studies bi-virus epidemics over large-scale networks. We set the rules of infection at the nodelevel and determine the dynamical law governing the evolution of the fraction of infected
