Stability of a Class of RDDE

ZHANG Qun Li 1,DONG Xiu juan 2(1.Mathematics Dept.of Heze University,Heze 274015,China;2.Heze Advanced Skilled Workers' School,274026,China)  
Based on the stability theory of functional differential equations,the stability of a class of functional differential equations with time-delay,namely,retarded differential difference equations(RDDE),is dealt with in this paper.In using the derivable property of functions to construct matrices of quadric form to judge whether the matrice is positive or negative definite,new sufficient conditions for the stability of zero solution of this class of RDDE are derived.At last,some simulatin examples are employed to illustrate the validity of the theory.
