Double Constacyclic Codes over Two Finite Commutative Chain Rings
Yun Fan, Hualu Liu
Many kinds of codes which possess two cycle structures over two special finite commutative chain rings, such as -additive cyclic codes and quasi-cyclic codes…
Asymptotic Properties of Quasi-Group Codes
Yun Fan, Liren Lin
This is a manuscript of a chapter prepared for a book. The good codes possess large information length and large minimum distance. A class of codes is said to be asymptotically goo…
Self-dual 2-quasi-cyclic Codes and Dihedral Codes
Yun Fan, Yuchang Zhang
We characterize the structure of 2-quasi-cyclic codes over a finite field F by the so-called Goursat Lemma. With the characterization, we exhibit a necessary and sufficient conditi…
Self-dual -quasi-abelian Codes
Liren Lin, Yun Fan
A kind of self-dual quasi-abelian codes of index over any finite field is introduced. By counting the number of such codes and the number of the codes of this kind whose re…
Constacyclic Codes over Commutative Finite Principal Ideal Rings
Yun Fan
For any constacyclic code over a finite commutative chain ring of length coprime to the characteristic of the ring, we construct explicitly generator polynomials and check polynomi…
-Additive Cyclic Codes Are Asymptotically Good
Yun Fan, Hualu Liu
We construct a class of -additive cyclic codes generated by pairs of polynomials, study their algebraic structures, and obtain the generator matrix of any…
