On the irreducibility and Galois group of Hecke polynomials

Paloma Bengoechea

Published 2017-03-08Version 1

Let T_{n,2k}(X) be the characteristic polynomial of the n-th Hecke operator acting on the space of cusp forms of weight 2k for the full modular group (k is any even positive integer >5). We show that if there exists n>1 such that T_{n,2k}(X) is irreducible and has the full symmetric group as Galois group, then the same is true of T_{p,2k}(X) for all primes p.
