摘要/描述

The existence and the global attractivity of a positive periodic solution of the delay differential equation y(t)=y(t)F[t,y(t-τ1(t)),…, y(t-τn(t))] are studied by using some techniques of the Mawhin coincidence degree theory and the constructing suitable Liapunov functionals. When these results are applied to some special delay bio-mathematics models, some new results are obtained, and many known results are improved.
