Linear Delay-Differential Systems with Commensurate Delays: An Algebraic Approach

The book deals with linear time-invariant delay-differential equations with commensurated point delays in a control-theoretic context. The aim is to show that with a suitable algebraic setting a behavioral theory for dynamical systems described by such eq

tems with respect to their general system-theoretic properties. To this end, an algebraic setting for the equations under consideration is developed. A thorough

purely algebraic study shows that this setting is well-suited for an examination of delay-differential systems from the behavioral point of view in modern systems theory. The central object is a suitably defined operator algebra which turns out to be an elementary divisor domain and thus provides the main tool for handling matrix equations of delay-differential
