Let \(p\) be the principal symbol of a hyperbolic (pseudo) differential operator of order \(m\) admitting at most double characteristic roots. Suppose that at each point \(\rho\) of the double characteristic manifold \(\Sigma\) of \(p\) the Hamiltonian matrix of \(p, F_{p}\), has a Jordan block of d

## Abstract In this paper, we are concerned with the problem of boundedness of solutions for the second order differential equation __x__ โ€ณ + __f__ (__x__ )__x__ โ€ฒ + __g__ (__x__ ) = __e__ (__t__ ), where __f__ , __g__ โˆˆ __C__ ^โˆž^(โ„) are odd functions and __e__ (__t__ ) โˆˆ __C__ ^โˆž^(โ„/โ„ค) is odd.
