It is shown that Maeda’s conjecture on eigenforms of level 1 implies that for every positive even d and every p in a density-one set of primes, the simple group PSL2(Fpd) occurs as the Galois group of a number field ramifying only at p. MSC (2010): 11F11 (primary); 11F80, 11R32, 12F12 (secondary).

On the irreducibility and Galois group of Hecke polynomials
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…
Applying modular Galois representations to the Inverse Galois Problem
For many finite groups, the Inverse Galois Problem can be approached through modular/automorphic Galois representations. This is a report explaining the basic strategy, ideas and methods behind some…
Automorphic Galois representations and the inverse Galois problem
A strategy to address the inverse Galois problem over Q consists of exploiting the knowledge of Galois representations attached to certain automorphic forms. More precisely, if such forms are…

On modular forms and the inverse Galois problem
In this article new cases of the Inverse Galois Problem are established. The main result is that for a fixed integer n, there is a positive density set of primes p such that PSL2(Fpn) occurs as the…

A Possible Generalization of Maeda’s Conjecture
We report on observations we made on computational data that suggest a generalization of Maeda’s conjecture regarding the number of Galois orbits of newforms of level N=1, to higher levels. They also…
Experimental evidence for Maeda's conjecture on modular forms
We describe a computational approach to the verification of Maeda's conjecture for the Hecke operator T2 on the space of cusp forms of level one. We provide experimental evidence for all weights less…
Functoriality and the inverse Galois problem
Abstract We prove that, for any prime ℓ and any even integer n, there are infinitely many exponents k for which $\mathrm {PSp}_n(\mathbb {F}_{\ell ^k})$ appears as a Galois group over $\mathbb {Q}$.…
Functoriality and the Inverse Galois problem II: groups of type B_n and G_2

NON-ABELIAN BASE CHANGE FOR TOTALLY REAL FIELDS
Let F be a number field. A cohomological Hecke eigen cusp form f on GL2(FA) for the adele ring FA of F is called a base change of f if L(s, f) = L(s, ρF ) for ρF = ρ ∣∣ Gal(Q/F ). When f exists, we…
