By using results on poles of L-functions and theta correspondence, we give a bound on b for (χ,b)-factors of the global Arthur parameter of a cuspidal automorphic representation π of a classical group or a metaplectic group where χ is a conjugate self-dual automorphic character and b is an integer which is the dimension of an irreducible representation of SL 2(). We derive a more precise relation when π lies in a generic global A-packet.

全局 Arthur 参数中的 Theta 对应关系和简单因子

通过使用极点上的结果L-函数和theta对应,我们给出一个界限为了χ,- 尖状自同构表示的全局 Arthur 参数的因子π一个经典群或一个元波群,其中χ是一个共轭自对偶自同构特征并且是一个整数,它是不可约表示的维数SL 2。当我们得出更精确的关系时π在于一个通用的全局A-包。
