Anomaly-free Hyperspherical Hamiltonian spaces for simple reductive groups
Guodong Tang, Chen Wan, Lei Zhang
In this paper, we provide a complete list of anomaly-free hyperspherical Hamiltonian spaces for simple reductive groups, as well as their conjectural dual spaces in the sense of BZ…

A relative trace formula identity for non-tempered spherical varieties
Chen Wan
In this paper, motivated by some previous works in residue method and the recent theory of the relative Langlands duality, we prove a relative trace formula identity that compares…

Strongly tempered hyperspherical Hamiltonian spaces
Zhengyu Mao, Chen Wan, Lei Zhang
In this paper, we give a complete list of strongly tempered hyperspherical Hamiltonian spaces. We show that the period integrals attached to the list contains many previously studi…
