Rank-Two Drinfeld Module over Elliptic Curves

Chuangqiang Hu, Ze-Dong Huang, Chang-An Zhao

Drinfeld modules, introduced by D.~V.~Drinfeld in the 1970s, were originally developed as a function field analogue of elliptic curves and have since become a central tool in the L…

Non-special Divisors, LCPs of Codes, and LCD Codes on Kummer Extensions

Huachao Zhang, Chang-An Zhao

Recently, constructions of linear complementary pairs (LCPs) of codes and linear complementary dual (LCD) codes on function fields have attracted considerable attention due to the…

On the Maximal Length of MDS Elliptic Codes

Haojie Chen, Chuangqiang Hu, Junjie Huang +1

The determination of the maximal length of maximum distance separable (MDS) codes arising from elliptic curves is a central problem in coding theory. For an elliptic curve over…

Weierstrass semigroups at totally ramified places of degree one on linearized function fields

Huachao Zhang, Chang-An Zhao

A linearized function field can be viewed as a Galois extension of a rational function field . For a totally ramified place of degree one in , we give a unifi…

Linear Complementary Pairs of Algebraic Geometry Codes via Kummer Extensions

Huang Junjie, Chen Haojie, Zhang Huachao +1

Due to their widespread applications, linear complementary pairs (LCPs) have attracted much attention in recent years. In this paper, we determine explicit construction of non-spec…

Pure Gaps at Many Places and Multi-point AG Codes from Arbitrary Kummer Extensions

Huachao Zhang, Chang-An Zhao

For a Kummer extension defined by the affine equation $y^{m}=\prod_{i=1}^{r} (x-\a_i)^{λ_i}$ over an algebraic extension of a finite field $\fq$, where $\la_i\in \Z\backslash\…
