Permanence and global stability for nonautonomous discrete model of plankton allelopathy.
For the system \(x_i(k+ 1)= x_i(k)\exp\{r_i- a_{i1} x_1(k)- a_{i2} x_2(k)-b_i x_1(k)x_2(k)\}\) with variable coefficients, \(i= 1,2\), sufficient conditions are given such that it is permanent. In the case of periodic coefficients sufficient conditions are given such that a periodic solution exists, and that this solution is globally stable, in case it is positive.
