Moscow State University, Moscow, Russia aut Precise Estimates of the Walk Speed of Solutions of Second-Order Linear Systems [Elektronische Daten] [M. Lysak] We consider some classes of nonautonomous second-order systems of differential equations whose coefficients are bounded by a given constant M, in particular, diagonal systems, triangular systems, and systems corresponding to a single equation. It is shown that the walk speeds of solutions of various systems from these classes fill up a certain interval, and precise estimates are obtained for the length of that interval in terms of the value of M.
