This paper, based on the tiny error rule (TER) in algebraic sum method, derived the criterion for correctly expressing errors with significant digit, for the first time. Then, according to the criterion, an important conclusion is further reached, n

In this paper, we study the uniform stability of linear delayed differential equationswith impulse time windows. By means of Lyapunov functions and Razumikhin technique combined with classification discussion technique, the criterion of uniform stabi
