Essay

In this thesis estimations of linear differential, difference and differential-difference systems have been obtained. Differential-difference systems with delay have been also investigated. Estimations of divergence uniform in delay and those depending on a postaction are obtained. A lot of place is also devoted to the solution of the problem of a spectrum control in systems with delay. Analytical dependencies for coefficients of feedback in the system of canonical and general types have been obtained. Critical case on the planc and in three- dimensional space.
