# Dynamical Systems and Population Persistence

Share this page
*Hal L. Smith; Horst R. Thieme*

The mathematical theory of persistence answers questions such as which
species, in a mathematical model of interacting species, will survive over
the long term. It applies to infinite-dimensional as well as to
finite-dimensional dynamical systems, and to discrete-time as well as to
continuous-time semiflows.

This monograph provides a self-contained treatment of persistence theory
that is accessible to graduate students. The key results for deterministic
autonomous systems are proved in full detail such as the acyclicity
theorem and the tripartition of a global compact attractor. Suitable
conditions are given for persistence to imply strong persistence even for
nonautonomous semiflows, and time-heterogeneous persistence results are
developed using so-called “average Lyapunov functions”.

Applications play a large role in the monograph from the
beginning. These include ODE models such as an SEIRS infectious
disease in a meta-population and discrete-time nonlinear matrix models
of demographic dynamics. Entire chapters are devoted to
infinite-dimensional examples including an SI epidemic model with
variable infectivity, microbial growth in a tubular bioreactor, and
an age-structured model of cells growing in a chemostat.
