A basic precept, came across through Robert Langlands and named through him the ''functoriality principle'' predicts family members among automorphic types on mathematics subgroups of alternative reductive teams. Langlands functoriality relates the eigenvalues of Hecke operators performing on the automorphic kinds on teams (or the neighborhood components of the ''automorphic representations'' generated through them). within the few cases the place such kin were probed, they've got resulted in deep mathematics outcomes. This publication stories one of many easiest common difficulties within the conception, that of touching on automorphic varieties on mathematics subgroups of GL (n, E) and GL (n, F) whilst E/F is a cyclic extension of quantity fields. (This is called the bottom switch challenge for GL (n) the matter is attacked and solved via the hint formulation. The ebook is determined by deep and technical effects got by means of a number of authors over the last two decades. it may possibly now not function an creation to them, yet, by way of giving whole references to the printed literature, the authors have made the paintings priceless to a reader who doesn't comprehend the entire points of the idea of automorphic varieties
