On the existence of positive periodic solution of a amensalism model with Holling II functional response

Qiaoxia Lin, Xiaoyan Zhou

Abstract


Sufficient conditions are obtained for the existence of positive periodic solution of the following discrete amensalism model with Holling II functional response

$$x_1(k+1)= x_1(k)\exp\Big\{ a_1(k)-b_1(k)x_1(k)-\di\frac{c_1(k)x_2(k)}{e_1(k)+f_1(k)x_2(k)}\Big\},$$

$$x_2(k+1)= x_2(k)\exp\big\{ a_2(k)-b_2(k)x_2(k)\big\},$$

where $\{b_{i}(k)\}, i=1, 2, \{c_1(k)\}\{e_1(k)\}, \{f_1(k)\}$ are all positive $\omega$-periodic sequences, $\omega $ is a fixed positive integer, $\{a_{i}(k)\}$ are $\omega$-periodic sequences, which satisfies \overline{a}_i=\frac{1}{\omega}\sum\limits_{k=0}^{\omega-1}a_i(k)>0, i=1,2$.
