A Note on Cyclotomic Function Fields with Quadratic Modulus
Haojie Chen, Chuangqiang Hu
A longstanding and important problem in algebraic geometry is the characterization of algebraic function fields. In this paper, we focus on the characterization problem for cycloto…

Infinitesimal deformations of Lie algebroid pairs
Dadi Ni, Zhuo Chen, Chuangqiang Hu +1
We study infinitesimal deformations of Lie algebroid pairs in the category of smooth manifolds enriched with a local Artinian algebra. Given a Lie algebroid pair , i.e. a Li…

New optimal function field towers over finite fields of quartic power
Chuangqiang Hu, Xiuwu Zhu
We introduce two new types of towers of Drinfeld modular curves. These towers originate from a specific domain and are analogous to the towers of rank-two Drinfeld m…
