Euler Characteristics of $SL_{4} (Z)$ and $GL_{4} (Z)$ , and their cohomological consequences

Jitendra Bajpai, Taiwang Deng

We compute the homological Euler characteristics of $SL_{4} (Z)$ and $GL_{4} (Z)$ with coefficients in arbitrary irreducible rational highest-weight r…

Yun's zeta function and the overorder zeta function for Gorenstein cubic orders

Taiwang Deng, Malors Espinosa

For every Gorenstein cubic $Z$ -order, we prove an identity equating Yun's zeta function, defined by counting finite-index submodules of the trace dual, with the explicit ov…

A trace formula derivation of the functional equation for symmetric square L-functions

Taiwang Deng, Dongsheng Wu

This paper revisits the functional equation of the symmetric-square $L$ -function from the perspective of trace formulas. We show that, for level-one holomorphic cusp forms and even…

A degenerate Whittaker criterion for $G L_{2 n}$

Taiwang Deng

Let $F$ be a non-Archimedean local field. Let $N$ be the unipotent radical of the standard parabolic subgroup of $G L_{2 n} (F)$ of type $(n, n)$ with fixed nondegenerate addit…

Stability of the exterior cube $γ$ -factors for $GL (6)$

Taiwang Deng, Dongming She

We prove the stability of the Langlands-Shahidi local $γ$ -factor for the exterior cube representation of $GL_{6}$ . More precisely, if $π_{1}$ and $π_{2}$ are irreducible admissi…

Relating Arthur packets of real unitary groups and $p$ -adic symplectic and orthogonal groups

Taiwang Deng, Chang Huang, Bin Xu +1

We establish an explicit correspondence of certain Arthur packets between real unitary groups and $p$ -adic symplectic or orthogonal groups. This allows one to compute Arthur packet…

Beyond Endoscopy for $GL (3, Q)$ : Isolation of the residual spectrum via Poisson Summation

Taiwang Deng, Malors Espinos

We extend to $GL (3, Q)$ the Poisson-summation method developed by Altuğ for $GL (2, Q)$ in Beyond Endoscopy. For a fixed prime and a family of factor…
