在对称的正方形上。不稳定扭曲字符

On the symmetric square. Unstable Twisted Characters

Yuval Z. Flicker, Dmitrii Zinoviev

摘要:

本文给出了由极大抛物子群的平凡表示导出的p-adic域上PGL(3)的表示π=I(\1)的(椭圆)扭曲(通过“转置逆”)特征的纯局部计算.这个计算与SL(2)到PGL(3)的自守和容许表示的[IV]的对称平方提升理论无关。它导致对称平方提升理论中的(不稳定的)基本引理的证明,即相应的球函数(在PGL(2)和PGL(3)上)是匹配的:它们具有匹配的轨道积分。

英文摘要:

We provide a purely local computation of the (elliptic) twisted (by "transpose-inverse") character of the representation π=I(\1) of PGL(3) over a p-adic field induced from the trivial representation of the maximal parabolic subgroup. This computation is independent of the theory of the symmetric square lifting of [IV] of automorphic and admissible representations of SL(2) to PGL(3). It leads to a proof of the (unstable) fundamental lemma in the theory of the symmetric square lifting, namely that corresponding spherical functions (on PGL(2) and PGL(3)) are matching: they have matching orbital integrals.
