本文证明了奇特征分裂有限域上不可约一般尖点表示的若干重数1定理,并定义了扭Gamma因子。然后证明了例外群的第一匡威定理,即,和-扭曲伽玛因子将唯一地决定的不可约一般尖点表示。
In this paper, we prove certain multiplicity one theorems and define twisted gamma factors for irreducible generic cuspidal representations of splitover finite fieldskof odd characteristic. Then we prove the first converse theorem for exceptional groups, namely,and-twisted gamma factors will uniquely determine an irreducible generic cuspidal representation of.
