Snippet: Around equilibrium E 5 , we can gain the same result from Fig. 8 . Under the condition that parameter a, d, σ take value 5.6923, 0.11, 0.2 and change value of Λ and c from 0.45102, 3.6062 to 0.51, 3.5972, respectively, which is a minor change, then the number of limit cycles will add one. Thus, the interior equilibrium E 5 is a stable weak focus of multiplicity two if (σ, Λ, d, a, c) = (0.2, 0.51, 0.11, 5.6923, 3.5962)......
