On impulsive Beverton-holt difference equations and their applications. (English) Zbl 1068.39005
The authors consider asymptotic properties of the impulsive Beverton-Holt difference equation \[ x_{n+1}=\frac{\alpha _nx_n}{1+B_nx_n},\;x_{pk}^{+}=b_kx_{pk}-d_k,\;n,k=1,2, \ldots , \] where \(p\) is a fixed positive integer. The results obtained are applied to an impulsive logistic equation with non-constant coefficients \[ x^{\prime }(t)=x(t)(r(t)-a(t)x(t)),\;x(\tau _k)=b_kx(\tau _k^{-})-d_k,\;\lim_{k\rightarrow \infty }\tau _k=\infty . \] In particular, sufficient extinction and non-extinction conditions are obtained for both equations.
