Stability research of dengue model with time delay
This paper studied the dengue fever model with time delay.This paper divided the time delay into four cases:(1)τ1 = τ2 = 0,(2)τ1 = τ,τ2 = 0,(3)τ1 = 0,τ2 = τ,(4)τ1 = τ,τ2 = τ,and studied the stability and Hopf bifurcation of the model on these three cases.At the end of this paper,we simulated the dengue model with time delay by using Matlab software,and gained the numerical condition of this model which appearing periodic solutions and Hopf bifurcation.On the first case τ1 = τ,τ2 = 0,the time delay threshold is τ0 = 0.6155; on the second case τ1 = 0,τ2 = τ,the time delay threshold is τ0 = 0.0490; on the third case τ1 = τ,τ2 = τ,the time delay threshold is τ0 = 3.5454.
