On rank one perturbations of Hamiltonian system with periodic coefficients
Mouhamadou Dosso, Arouna G. Y. Traore, Jean-Claude Koua Brou
From a theory developed by C. Mehl, et al., a theory of the rank one perturbation of Hamiltonian systems with periodic coefficients is proposed. It is showed that the rank one pert…
