广义双偶Self-Dual码的完全重量计数器

Complete Weight Enumerators of Generalized Doubly-Even Self-Dual Codes

Gabriele Nebe, H. -G. Quebbemann, E. M. Rains, N. J. A. Sloane

摘要:

对于任意2的幂q,我们用q矩阵描述可逆复q群的有限子群,在此子群下q元域上广义双偶自对偶码的完全重量计数元是不变的.在q=4的情况下,给出了不变环的一个显式描述,并给出了这类码的极值性的一些应用。

英文摘要:

For any q which is a power of 2 we describe a finite subgroup of the group of invertible complex q by q matrices under which the complete weight enumerators of generalized doubly-even self-dual codes over the field with q elements are invariant. An explicit description of the invariant ring and some applications to extremality of such codes are obtained in the case q=4.
