Norkin S.B. Differential Equations of the Second Order With Retarded Argument

AMS, 1972. - 285 Pages.The theory of differential equations with deviating arguments is a relatively new and rapidly developing branch of the theory of ordinary differential equations. Numerous research papers have been devoted to this theory. There are also a few monographs which in part or entirely are concerned with various aspects of differential equations with deviating arguments.
In this book we present and discuss several results presented in the seminar on differential equations with deviating arguments conducted by L. Ё. Ersgorc.
