A Reduction Method for Higher Order Variational Equations of Hamiltonian Systems

Ainhoa Aparicio, Jacques-Arthur Weil

Let $\mathbf{k}$ be a differential field and let $[A]:Y^{\prime }=AY$ be a linear differential system where $A\in \mathrm{Mat}(n,\mathbf{k})$. We say that $A$ is in a reduced form…
