Mathematical structures of epidemic systems
TL;DR: Linear models and strongly nonlinear models were used in this paper to model the spatial heterogeneity and age structure of a population in an environment with positive feedback and positive feedback systems.
Journal ArticleDOI
Threshold and stability results for an age-structured epidemic model.
TL;DR: A mathematical model for an epidemic spreading in an age-structured population with age-dependent transmission coefficient is formed as an abstract Cauchy problem on a Banach space and some conditions which guarantee the existence and uniqueness for non-trivial steady states of the model are derived.

Rational Matrix Equations in Stochastic Control
TL;DR: In this article, the Riccati equation is solved for linear stochastic systems and linear mappings on ordered vector spaces are obtained using the Newtons method, which is a generalization of the Newton method.
Journal ArticleDOI
On a new perspective of the basic reproduction number in heterogeneous environments.
TL;DR: A new definition of R0 is introduced based on the generation evolution operator (GEO), which has intuitively clear biological meaning and can be applied to structured populations in any heterogeneous environment.

Theory of cones
TL;DR: In this paper, a survey of the aspects of archimedian partially ordered finite-dimensional real vector spaces and order preserving linear maps which do not involve spectral theory is presented.
