对于GL(2)的酉非二面角尖点自守表示,我们得到了强重数1定理的一个精确的改进。给定GL(2)的两个酉尖点自守表示不是扭等价的,我们也发现了Hecke特征值不相等的地方的数量的急剧下界,对于一般和非二面角的情况。然后,我们构造的例子来证明这些结果是尖锐的。
We obtain a sharp refinement of the strong multiplicity one theorem for the case of unitary non-dihedral cuspidal automorphic representations for GL(2). Given two unitary cuspidal automorphic representations for GL(2) that are not twist-equivalent, we also find sharp lower bounds for the number of places where the Hecke eigenvalues are not equal, for both the general and non-dihedral cases. We then construct examples to demonstrate that these results are sharp.
