Jordan canonical forms of a rank-k perturbation of symplectic matrices and the fundamental solutions of Hamiltonian systems are presented on the basis of work done by C. Mehl et, al.. Small rank-k perturbations of Mathieu systems are anal

A theory of rank $k\ge 2$ perturbation of symplectic matrices and Hamiltonian systems with periodic coefficients using a base of isotropic subspaces, is presented. After showing that the fundamental matrix ${\displaystyle \left(\widetilde{X}(t)\right

In this paper we give a constructive method for rational C k finite element method in R 2 for quadrilateral. For k ⩾ 2 , the usual polynomials splines require some supersmoothness at the vertices of the quadrilateral, even when dealing with macro-e

Resume Etant donne une courbe spline definie par un grand nombre de points, il est parfois interessant de reduire la base de donnees, c'est-a-dire extraire un sous-ensemble permettant la reconstruction d'une courbe approchee a une tolerance donnee. L
