Vi. Kuznetsova et Vg. Kurbatov, Stability of linear systems described by integral equations with slowly varying kernels, AUT REMOT R, 61(6), 2000, pp. 933-944
Estimates guaranteeing the stability of systems described by Volterra integ
ral equations of the second kind are determined. In particular, these estim
ates reveal the stability of equations whose kernels vary slowly in time.
