Estimates of solutions of some systems of differential equations with large retardation

The behavior of the solutions of differential equations with asymptotically large retardation is studied. In the case of linear systems with bounded coefficients and a class of nonlinear differential equations, estimates are derived which depend explicitly on the retardation.Translated from Matematicheskie Zametki, Vol. 6, No. 4, pp. 483–488, October, 1969.
