In this paper, we consider a class of n species Lotka-Volterra systems with time delays and establish sufficient conditions which ensure the systems to be permanent. We improve and extend the known conditions of the permanence in Lu and Lu (2008) [4], Lu et al. ( 2010) [5] and Nakata and Muroya (201
In this paper we consider the permanence of the following Lotka᎐Volterra Ž . Ž . Ä w discrete competition system with delays k , k , l , and l : .x4 l . We show the system is permanent for all nonnegative integers k , k , l , and 2 1 2 1 l , if and only if -1 and -1 hold. ᮊ 2001 Academic Press 2 1
