基于F_4上二次双循环码的F_4 + uF_4-提升的新的极值二元self-dual码
New extremal binary self-dual codes from F_4 + uF_4-lifts of quadratic double circulant codes over F_4
摘要：
本文对F_4 + uF_4和F_4应用二次二重循环码和二次加边二重循环码的构造，得到了长度分别为56和64的极值二元自对偶码。利用二进制扩张定理和环扩张形式，得到了7个长度为58的极值自对偶二进制码，24个长度为66的极值自对偶二进制码和29个长度为68的极值自对偶二进制码，它们都具有新的权计数器，更新了文献中所有已知的极值自对偶码的列表.
英文摘要：
In this work, quadratic double and quadratic bordered double circulant constructions are applied to F_4 + uF_4 as well as F_4, as a result of which extremal binary self-dual codes of length 56 and 64 are obtained. The binary extension theorems as well as the ring extension version are used to obtain 7 extremal self-dual binary codes of length 58, 24 extremal self-dual binary codes of length 66 and 29 extremal self-dual binary codes of length 68, all with new weight enumerators, updating the list of all the known extremal self-dual codes in the literature.
