标题： Some restrictions on the weight enumerators of near-extremal ternary self-dual codes and quaternary Hermitian self-dual codes

摘要： 我们给出关于长度可被$12$整除的三元近极小自对偶码的重量枚举式的限制，以及长度可被$6$整除的四元近极小共轭自对偶码的重量枚举式的限制。 我们考虑存在长度为$12m$的三元近极小自对偶码的重量枚举式，其中$m =3,4,5,6$成立。 同时我们考虑存在长度为$6m$的四元近极小共轭自对偶码的重量枚举式，其中$m =4,5,6$成立。 显示英文摘要

摘要： We give restrictions on the weight enumerators of ternary near-extremal self-dual codes of length divisible by $12$ and quaternary near-extremal Hermitian self-dual codes of length divisible by $6$. We consider the weight enumerators for which there is a ternary near-extremal self-dual code of length $12m$ for $m =3,4,5,6$. Also we consider the weight enumerators for which there is a quaternary near-extremal Hermitian self-dual code of length $6m$ for $m =4,5,6$.
