The Efficiency of Perturbations in the Class of Linear Hamiltonian Systems / T. V. Salova. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2015. № 6. P. 48-52 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 274-277].

It is proved that the set of all limiting values of solutions' arbitrary indicators under uniformly small perturbations of coefficients of a linear Hamiltonian system is the same as the similar set obtained by uniformly small Hamiltonian perturbations.

Key words: linear systems, Hamiltonian systems, Lyapunov exponents, oscillation, wandering.
