My key result in this field is a constructive explanation of the Ziegler-Bottema paradox of destabilization by small dissipation of reversible and Hamiltonian systems . It is based on the original perturbation technique that I have developed for the multiparameter families of non-self-adjoint boundary eigenvalue problems and its combination with the methods of singularity theory . My results stimulated considerable research activity in engineering and physics and lead to identification of similar phenomena in seemingly unrelated applications [3-5].
