    "abstract": "We review Migdal\u0027s Theory of Finite Fermi Systems and its application to the\nstructure of nuclei. The theory is an extension of Landau\u0027s Theory of\nInteracting Fermi Systems. In the first part the basic formulas are derived\nwithin the many body Green functions approach. The theory is applied to\nisovector electric giant resonances in medium and heavy mass nuclei. The\nparameterizations of the enormalized effective ph-interaction and the effective\noperators are discussed. It is shown that the number of free parameters are\nrestricted due to conservation laws. We also present an extension of Migdal\u0027s\ntheory, where the low-lying phonons are considered in a consistent manner. The\nextended theory is again applied to the same isovector electric giant\nresonances and to the analysis of $(\\alpha,\\alpha^\\prime)$ reaction data. We\npoint out that the extended theory is the appropriate frame for self consistent\nnuclear structure calculations starting from effective Lagrangians and\nHamiltonians.",
