Dynamics of Gilpin-Ayala competition model with random perturbation

open access: yes, 2010
In this paper we study the Gilpin-Ayala competition system with random perturbation which is more general and more realistic than the classical Lotka-Volterra competition model.

A Perturbation Theory for Ergodic Properties of Markov Chains [PDF]

open access: yes, 2000
Perturbations to Markov chains and Markov processes are considered. The unperturbed problem is assumed to be geometrically ergodic in the sense usually established through use of Foster-Lyapunov drift conditions.
