Operator Semigroups for Functional Differential Equations with Delay

W. M. Ruess, W. H. Summers
1994 Transactions of the American Mathematical Society  
We show that a strongly continuous operator semigroup can be associated with the functional differential delay equation jc'(í) + ax(t) + Bx{t) B F(xt), í > 0
