Gabidulin类码的自同构群

Automorphism groups of Gabidulin-like codes

Dirk Liebhold, Gabriele Nebe

摘要:

设K是k上f次循环伽罗瓦扩张,T是伽罗瓦群的生成元.对于任何v=(v_1,.,v_m)\in K^m,使得v在k上线性无关,并且任何0这种结构统一了文献中的结构。本文研究了K-线性码的秩度量自同构群,并确定了它们的秩度量自同构群。

英文摘要:

Let K be a cyclic Galois extension of degree f over k and T a generator of the Galois group. For any v=(v_1,... , v_m)\in K^m such that v is linearly independent over k, and any 0< d < m the Gabidulin-like code C(v, T , d) is a maximum rank distance code in the space of f times m matrices over k of dimension fd. This construction unifies the ones available in the literature. We characterise the K-linear codes that are Gabidulin-like codes and determine their rank-metric automorphism group.
