Tame ramification; Galois extension; Supersingular elliptic curve
Résumé :
[en] This paper concerns the tame inverse Galois problem. For each prime number l, we construct
infinitely many semistable elliptic curves over Q with good supersingular reduction at l. The
Galois action on the l-torsion points of these elliptic curves provides tame Galois realizations of
GL_2(F_l) over Q.
