Abstract :
This bibliography is an attempt to survey the writings, in various fields of study, which deal with functions with retarded argument. This problem is characterized by a response to a stimulus which is identical to a normal response except that it is delayed in time. Some situations in which this transportation lag occurs include process control (distance-velocity lag), control of thermal systems (including control of nuclear reactors), rocket motor combustion (ignition and combustion lags), traveling waves, magnetic amplifiers, human link in control systems (reaction time), high-speed aerodynamic control, and economic systems (period of gestation or production lag). A bibliography is presented which lists and abstracts a number of the references dealing with this problem. Relevant references in two major categories have been omitted in this bibliography. Foreign language works and pure mathematical treatments have not been listed. A comprehensive list of these references may be found in an excellent bibliography on the subject.1 The format of the reference listings is an adaptation of standard bibliographical format convenient to the type of material presented. References are lettered according to the author´s surname, rather than numbered, to facilitate future additions without breaking the continuity of the reference notation.
