3维Hamming图中覆盖半径为1且具有第二特征值的完全正则码

Completely regular codes with covering radius 1 and the second eigenvalue in 3-dimensional Hamming graphs

Ivan Mogilnykh, Anna Taranenko, Konstantin Vorob'ev

AI总结:

本文研究Hamming图中的完全正则码,依据q和交叉阵列完成H(3,q)内覆盖半径为1且具第二特征值情形的分类,并补全相关一般分类。

摘要:

我们依据q和交叉阵列,对Hamming图H(3,q)中覆盖半径为1且具有第二特征值的完全正则码进行了分类。得益于Meyerowitz、Mogilnykh和Valyuzenich的工作,我们的结果完善了对任意n的Hamming图H(n,q)中覆盖半径为1且具有第二特征值的完全正则码,以及H(3,q)中覆盖半径为1的完全正则码的分类。

英文摘要:

We obtain a classification of the completely regular codes with covering radius 1 and the second eigenvalue in the Hamming graphs H(3,q) up to q and intersection array. Due to works of Meyerowitz, Mogilnykh and Valyuzenich, our result completes the classifications of completely regular codes with covering radius 1 and the second eigenvalue in the Hamming graphs H(n,q) for any n and completely regular codes with covering radius 1 in H(3,q).
