Global Stability of Cycles: Lotka-Volterra Competition Model With Stocking

In this article, we prove that in connected metric spaces n - cycles are not globally attracting (where n S 2 ). We apply this result to a two species discrete-time Lotka-Volterra competition model with stocking. In particular, we show that an n - cycle cannot be the ultimate life-history of evolution of all population sizes. This solves Yakubu's conjecture but the question on the structure of the boundary of the basins of attractions of the locally stable n - cycles is still open.
