An equation = A(t)u + B(t)F(t,u(t - τ)), u(t) = v(t),-τ ≤ t ≤ 0 is considered, A(t) and B(t) are linear operators in a Hilbert space H, = , F : H → H is a non-linear operator, τ > 0 is a constant. Under some assumption on A(t),B(t) and F(t,u) sufficient condittions are given for the solution u(t) to exist globally, i.e, for all t ≥ 0, to be globally bounded, and to tend to zero as t →∞.
