We studied a class of generalized n-species non-autonomous cooperative Lotka–Volterra (L-V) systems with time delays. obtained new criteria on the dynamic properties systems. First, we boundedness and permanence system using inequality analysis technique comparison method. Then, existence positive periodic solutions was investigated coincidence degree theory. The global attractivity by construc...

A two-dimensional system of differential equations with delay modelling the glucose-insulin interaction processes in human body is considered. Sufficient conditions are derived for unique positive equilibrium to be globally asymptotically stable. They given terms global attractivity fixed point a limiting interval map. The existence slowly oscillating periodic solutions shown case when unstable...
