Modular forms and some cases of the inverse Galois problem

Number Theory 2015-09-01 v1

Abstract

We prove new cases of the inverse Galois problem by considering the residual Galois representations arising from a fixed newform. Specific choices of weight 33 newforms will show that there are Galois extensions of Q\mathbb{Q} with Galois group PSL2(Fp)PSL_2(\mathbb{F}_p) for all primes pp and PSL2(Fp3)PSL_2(\mathbb{F}_{p^3}) for all odd primes p±2,±3,±4,±6(mod13)p \equiv \pm 2, \pm 3, \pm 4, \pm 6 \pmod{13}.
