Abstract

Sufficient conditions are obtained for the global attractivity of the positive equilibrium and boundary equilibria of the following two-species competitive system with nonlinear inter-inhibition terms \[ \frac{dy_1(t)}{dt} = y_1(t)\Bigg[r_1-a_1y_1-\frac{b_1\int_{-\infty}^{t}K_2(t-s)y_2(s)ds}{1+\int_{-\infty}^{t}K_2(t-s)y_2(s)ds}\Bigg],\ \ \ \frac{dy_2(t)}{dt} = y_2(t)\Bigg[r_2-a_2y_2-\frac{b_2\int_{-\infty}^{t}K_1(t-s)y_1(s)ds}{1+\int_{-\infty}^{t}K_1(t-s)y_1(s)ds}\Bigg], \] where \(r_i, a_i, b_i, i=1,2\) are all positive constants. The results not only improve but also complement the main results of [B. G. Chen, J. Math. Computer Sci., \(\bf 16 \) (2016), 481--494].
