A periodically forced Beverton-Holt equation. (English) Zbl 1023.39013
The authors present an open problem: to prove or disprove the following assertions for $$p\geq 3$$.
(a) The periodically forced Beverton-Holt equation $x_{n+1}=\frac{rK_n}{K_n+(r-1)x_n}x_n, \quad n=0, 1, 2, \ldots,$ has a positive $$p$$-periodic solution $$\{y_n\}$$, and it is globally attracting for $$x_0>0$$, where $$r>1$$ and $$\{K_n\}$$ is a sequence of positive numbers with a base period $$p\geq 1$$.
(b) If $$p>2$$, the strict inequality $$av(y_n)<av(K_n)$$ holds. Here $$av(y_n)=\frac{1}{p}\sum_{i=0}^{p-1}y_i$$.
