我们表明,如果限制的分解群在p的p-进伽罗瓦表示附加到一个成员的希达家庭的椭圆模尖形式是不分裂的,那么它是不分裂的,但这个家庭的许多成员。我们解释了这一结果的相关性的一个问题,格林伯格的本地分裂行为的普通模块化伽罗瓦表示。
We show that if the restriction to the decomposition group at p of the p-adic Galois representation attached to one member of a Hida family of elliptic modular cusp forms is non-split then it is non-split for all but finitely many members of this family. We explain the relevance of this result to a question of Greenberg on the local splitting behavior of ordinary modular Galois representations.
