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

Makoto Araya, Masaaki Harada

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…

Self-dual codes over $F_{5}$ and $s$ -extremal unimodular lattices

Masaaki Harada

New $s$ -extremal extremal unimodular lattices in dimensions $38$ , $40$ , $42$ and $44$ are constructed from self-dual codes over $F_{5}$ by Construction A. In the process of…

Construction of extremal Type II $Z_{2 k}$ -codes

Masaaki Harada

We give methods for constructing many self-dual $Z_{m}$ -codes and Type II $Z_{2 k}$ -codes of length $2 n$ starting from a given self-dual $Z_{m}$ -code and Type…
