Helicoidal surfaces of non-lightlike frontals in Lorentz-Minkowski 3-space
Kaixin Yao, Wei Zhang
In this paper, we define two types of helicoidal surfaces of non-lightlike frontals in Lorentz-Minkowski 3-space and investigate when they become lightcone framed base surfaces. Mo…

Unitary Friedberg-Jacquet periods and their twists: Relative trace formulas
Spencer Leslie, Jingwei Xiao, Wei Zhang
In a companion paper, we formulated a global conjecture for the automorphic period integral associated to the symmetric pairs defined by unitary groups over number fields, generali…

Unitary Friedberg-Jacquet periods and their twists: Fundamental lemmas
Spencer Leslie, Jingwei Xiao, Wei Zhang
We formulate a global conjecture for the automorphic period integral associated to the symmetric pairs defined by unitary groups over number fields, generalizing a theorem of Walds…
