Abstract :
Sufficient conditions are obtained for the global attractivity of the positive equilibrium of the delaylogistic
equation with impulsive effect
N˙ (t) = r(t)N(t) K−Np(t−τ)
K+c(t )Np(t−τ) ,
N(τ+k ) = N(τk ) exp Ik ln N(τk )
p√K ,
where r(t), c(t) are continuous functions, p,K, τ are positive constants, and {τk}∞k =1 denotes the
sequence of impulsive time which assumed to be strictly increasing. Some special cases are also
considered.
