| Abstract: | A kind of generalized Lotka Volterra systems with competition spread is considered in this paper. By using differential inequalities we discuss the existence of a positive almost periodic solution and its stability under disturbances from the hull. The results for Lotka Volterra systematic almost periodic solution by QINFaJin and LUO GuiLie are generalized and improved. |
