This paper is to solve several problems on the global attractivity of the zero solution of the nonautonomous difference equation $x_{n + 1} - x_n + P_n x_{n - k_n } = 0,n \in \mathbb{Z} (0)$ , where P n is a sequence ...
The existence and the global attractivity of a positive periodic solution of the delay differential equation y·(t)=y(t)F[t, y(t-τ 1(t)),...,y(t-τ n(t))] are studied by using some techniques of the Mawhin coincidenc...

The global attractivity of the zero solution of the delay functional differential equation x(t)+ [1+x(t)]F(t, x(·)) =0 is studied by using a new technique. When this result is applied to some special delay bio-mathem...
