Abstract
The paper deals with the operator differential equation y(2n)(t)+Ay(n)(t)+By(t)=0, where A and B are self-adjoint commuting operators, in a Hilbert space. Criteria are established for stability and stabilization of solutions at infinity. In the case of growing solutions, their asymptotic behavior is investigated. Examples are given from mathematical physics. Bibliography: 21 titles.
