本文研究了从SL₃三重覆盖到PGL₃的Shimura提升,并通过全球周期非消失性刻画提升像,从而建立基本引理。

摘要:

经典的Shimura对应将双覆盖的SL₂上的自守表示提升到PGL₂上的自守表示。在这里,我们朝着建立一个相对迹公式迈出关键一步,该公式将给出一个新的全球Shimura提升,从SL₃的三重覆盖到PGL₃,并且刻画该提升的像。该刻画将通过某个涉及分裂SO₈(𝐀)上自守最小表示Θ_SO₈空间中函数的特定全球周期的非消失性来实现,这与Bump、Friedberg和Ginzburg于2001年提出的猜想一致。在本文中,我们首先分析一个涉及该周期的全球分布,并证明其为因子可分解轨道积分之和。同样的情况也适用于附属于SL₃三重覆盖的Kuznetsov分布。然后,我们匹配相应的局部轨道积分,即对于球面Hecke代数的单位元素;也就是说,我们建立了基本引理。

英文摘要:

The classical Shimura correspondence lifts automorphic representations on the double cover of $SL_2$ to automorphic representations on $PGL_2$. Here we take key steps towards establishing a relative trace formula that would give a new global Shimura lift, from the triple cover of $SL_3$ to $PGL_3$, and also characterize the image of the lift. The characterization would be through the nonvanishing of a certain global period involving a function in the space of the automorphic minimal representation $Θ_{SO_8}$ for split $SO_8({\mathbb{A}})$, consistent with a 2001 conjecture of Bump, Friedberg and Ginzburg. In this paper, we first analyze a global distribution on $PGL_3({\mathbb{A}})$ involving this period and show that it is a sum of factorizable orbital integrals. The same is true for the Kuznetsov distribution attached to the triple cover of $SL_3({\mathbb{A}})$. We then match the corresponding local orbital integrals for the unit elements of the spherical Hecke algebras; that is, we establish the Fundamental Lemma.
