review text: Let \(F\) be a finite extension of \(\mathbb Q_p\). For each integer \(n\geq 1\), the author constructs a bijection from the set \(\mathcal G_F^0(n)\) of isomorphism classes of irreducible degree \(n\) representations of the (absolute) Weil group of \(F\), onto the set \(\mathcal A_F^0(n)\) of isomorphism classes of smooth irreducible supercuspidal representations of \(\text{GL}_n(F)\). Those bijections preserve epsilon factors for pairs and hence the author obtains a proof of the Langlands conjectures for \(\text{GL}_n\) over \(F\), which is more direct than that of \textit{M. Harris} and \textit{R. Taylor} in [The geometry and cohomology of some simple Shimura varieties. (Annals of Math. Studies 151, Princeton Univ. Press), (2001; Zbl 1036.11027)]. The author's approach is global and analogous to the derivation of local class field theory from global class field theory. He starts with a result of Kottwitz and Clozel on the good reduction of some Shimura varieties and uses a trick of Harris, who constructs non-Galois automorphic induction in certain cases.
