Abstract
A new approach to finding analytical solutions of linear delay algebraic-differential equations is suggested. The analytical form of the solution is determined in terms of the infinite set of eigenvalues of a parametric matrix whose entries are the delay-time operators exp(–pτ), where p is the Laplace operator. In order to compute constants in the solution of the homogeneous equations, one must analytically find higher derivatives at the input of the delay operator. The problem of stopping the computation of the infinite spectrum upon determining a certain number of its components is discussed. Bibliography: 5 titles.
