Collective Normal Modes of Ensembles of Magnetic Tubes: Applications to Coronal Arcades and Multi-Stranded Loops
Using the T-matrix theory, we have performed an analytical study of the collective fast normal modes of an arbitrary system of loops. The obtained results allow to assess the dynamical effects of the interaction of loops and the frequency shifts with respect to the individual loops in an arcade as a function of the number of tubes. Furthermore, the
