具有大指数的Hecke代数T_k
The Hecke Algebra T_k has Large Index
摘要:
设T_k表示作用在权k和水平N的新形式上的Hecke代数。我们证明了功率的p除以指数的T_k内其正规化增长至少与k线性(固定N),回答一个问题的塞尔。我们还应用我们的方法给启发式的证据,对最近的Astructures的Buzzard和Mazur。
英文摘要:
Let T_k denote the Hecke algebra acting on newforms of weight k and level N. We prove that the power of p dividing the index of T_k inside its normalisation grows at least linearly with k (for fixed N), answering a question of Serre. We also apply our method to give heuristic evidence towards recent conjectures of Buzzard and Mazur.
