Positive periodic solutions of nonautonomous delay competitive systems with weak Allee effect

Periodic Solutions for n-Species Lotka-Volterra Competitive Systems with Pure Delays

“…In [3], the authors considered the following nonautonomous delay -species competitive systems with delays:…”

Global attractivity of n-species competition systems with pure distributed delays

“…In recent years, population dynamical competition systems have been studied extensively (see [1]- [14] and the references therein) and some of them are described as autonomous or non-autonomous non-delayed differential equations; see [2]- [6] and the references therein. But most of them are on the dynamics of population Lotka-Volterra competition systems with delays, which are useful for the control of the population of mankind, animals and the environment [7]- [14]. For example, Lv, Yan and Lu [7] considered the following competitor-competitor-mutualist Lotka-Volterra systems with pure delayṡ…”

Existence and global attractivity of positive almost periodic solutions for a kind of fishing model with pure-delay

“…It is well known that Mawhin's continuation theorem of coincidence degree theory is an important method to investigate the existence of positive periodic solutions of some kinds of non-linear ecosystems (see [3,4,5,6,7,8,15,16,22,25,33,34]). However, it is difficult to be used to investigate the existence of positive almost periodic solutions of non-linear ecosystems.…”
