Numerical solution of constant coefficient linear delay differential equations as abstract Cauchy problems

In this paper we present an approach for the numerical solution of Delay Di erential Equations y 0 (t) = Ly (t) +My (t ) t 0 y (t) = ' (t) t 0; (1) where > 0, L;M 2 C I m m and ' 2 C ([ ; 0] ; C I m ), di erent from the classical step-by-step method. We restate (1) as an abstract Cauchy problem and then we discretize it in a system of Ordinary Differential Equations. The scheme of discretization is proved to be convergent. Moreover the asymptotic stability is investigated for two signi cant classes of asymptotically stable problems (1).
