Changement de Base et Induction Automorphe Pour $$\mathrm{GL}_n$$ en Caractéristique non Nulle
 Mémoires de la Société Mathématique de France 2011; 194 pp; softcover Number: 124 ISBN-10: 2-85629-311-5 ISBN-13: 978-2-85629-311-9 List Price: US$45 Member Price: US$36 Order Code: SMFMEM/124 Let $$E/F$$ be a finite cyclic extension of local or global fields, of degree $$d$$. The theory of base change from $${\rm GL}_n(F)$$ to $${\rm GL}_n(E)$$ and the theory of automorphic induction from $${\rm GL}_m(E)$$ to $${\rm GL}_{md}(F)$$ are two instances of Langlands' functoriality principle: when $$F$$ is local, they correspond respectively to restriction to $$E$$ of representations of the Weil-Deligne group of $$F$$, and induction to $$F$$ of representations of the Weil-Deligne group of $$E$$. If $$F$$ is a finite extension of a $$p$$-adic field $$\mathbb {Q}_p$$, these theories were established long ago (Arthur-Clozel, Henniart-Herb). In this memoir the authors extend them to the case where $$F$$ is a non-Archimedean locally compact field of positive characteristic. They also prove, for a global functions field $$F$$, that these two local theories are compatible with the global maps of base change and automorphic induction deduced, via the Langlands correspondence proved by Lafforgue, from restriction and induction of global Galois representations.
