Sufficient and Necessary Conditions for the Permanence of a Discrete Model with Beddington-DeAngelis Functional Response
We give a sufficient and necessary condition for the permanence of a discrete model with Beddington-DeAngelis functional response with the form x(n+1) = x(n)exp{a(n)-b(n)x(n)-c(n)y(n)/(α(n)+β(n)x(n)+γ(n)y(n))},y(n+1)=y(n)exp{-d(n)+f(n)x(n)/(α(n)+β(n)x(n)+γ(n)y(n))}, where a(n),b(n),c(n),d(n),f(n),α(...
