## Abstract We consider Hamiltonian matrices obtained by means of symmetric and positive definite matrices and analyse some perturbations that maintain the eigenvalues on the imaginary axis of the complex plane. To obtain this result we prove for such matrices the existence of a diagonal form or, a

## Abstract In this paper we study a generalized symplectic fixed‐point problem, first considered by J. Moser in [20], from the point of view of some relatively recently discovered symplectic rigidity phenomena. This problem has interesting applications concerning global perturbations of Hamiltonia

## Abstract We establish some new oscillation criteria for the matrix linear Hamiltonian system __X__ β€² = __A__ (__t__)__X__ + __B__ (__t__)__Y__, __Y__ β€² = __C__ (__t__)__X__ –__A__ \*(__t__)__Y__ by using a new function class __X__ and monotone functionals on a suitable matrix space. In doing so,

## Abstract The problem of designing strategies for optimal feedback control of non‐linear processes, specially for regulation and set‐point changing, is attacked in this paper. A novel procedure based on the Hamiltonian equations associated to a bilinear approximation of the dynamics and a quadrat
