Cette thèse a pour objet d'étudier l'influence de la discrétisation d'une équation différentielle sur les variétés stables et instables dans deux exemples concrets : l'équation logistique et l'équation du pendule. L'équation logistique est

Inaccurate description of the equilibrium can yield to spurious effects in gyrokinetic turbulence simulations. Also, the Vlasov solver and time integration schemes impact the conservation of physical quantities, especially in long-term simulations. E

We consider the discretization q(t+\epsilon)+q(t-\epsilon)-2q(t)=\epsilon^{2}\sin\big(q(t)\big), $\epsilon>0$ a small parameter, of the pendulum equation $ q '' = \sin (q) $; in system form, we have the discretization q(t+\epsilon)-q(t)=\epsilon p(t+

We consider the discretization y(t+\epsilon)=y(t-\epsilon)+2\epsilon\big(1-y(t)^{2}\big), $\epsilon>0$ a small parameter, of the logistic differential equation $y'=2\big(1-y^{2}\big)$, which can also be seen as a discretization of the system {y'=2\bi

The purpose of this dissertation is to study how the discretization of a differential equation affects, the stable and unstable manifolds in two concrete examples: the logistic equation and the pendulum equation. The logistic equation is equivalent t
