Let be a number field, and let be a reductive group over , and let be a congruence subgroup of . I can hear BC objecting that this doesn’t make sense without extra choices; if you have such an objection, … Continue reading
There are nonliftable weight one forms modulo p for any p
Let be any prime. In this post, we show that there is an integer prime to such that has a torsion class of order . Almost equivalently, there exists a Katz modular form of level and weight one over which … Continue reading
