Plans, Bernat; Vila, Núria Tame \(A_{n}\)-extensions of \({\mathbb Q}\). (English) Zbl 1057.12003 J. Algebra 266, No. 1, 27-33 (2003). The authors prove the following result: For every positive integer \(n\) and every finite set \(S\) of prime numbers, there exist infinitely many disjoint extensions of \({\mathbb Q},\) each one obtained as the splitting field over \({\mathbb Q}\) of a totally real monic polynomial \(f(x)\in Z[x]\) of degree \(n\) such that the discriminant of \(f(x)\) is not divisible by any prime number of \(S\) and such that \(f(x)\) has Galois group \(A_n\) over \({\mathbb Q}.\) Reviewer: Michael Dettweiler (Heidelberg) Cited in 1 ReviewCited in 4 Documents MSC: 12F12 Inverse Galois theory 11R09 Polynomials (irreducibility, etc.) 11R32 Galois theory Keywords:alternating group; tame extension; Hilbert’s irreducibility theorem PDFBibTeX XMLCite \textit{B.
