Relating Arthur packets of real unitary groups and -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 -adic symplectic or orthogonal groups. This allows one to compute Arthur packet…

Limit Values of Character Sums in Frobenius Formula of Three Permutations
Dun Liang, Bin Xu, Wenyan Yang
We study the asymptotic behaviour of the character summation part of the Frobenius formula for three conjugacy classes of the symmetric groups. When two conjugacy classes contain f…
