Abstract:  We investigate the spectral theory for the system $Ju’+qu=w(\lambda u+f)$ of ordinary differential equations where $J$ is constant invertible skew-hermitian matrix while $q$ is a hermitian and $w$ a non-negative matrix whose entries are distributions of order $0$. A major obstacle is the fact that, in general, the unique continuation of solutions of the differential equation is not possible. Basic information on distributions will be provided.
