Congruences for modular forms mod 2 and quaternionic $S$-ideal classes (1701.07864v2)
Published 26 Jan 2017 in math.NT
Abstract: We prove many simultaneous congruences mod 2 for elliptic and Hilbert modular forms among forms with different Atkin--Lehner eigenvalues. The proofs involve the notion of quaternionic $S$-ideal classes and the distribution of Atkin--Lehner signs among newforms.
