循环轨道标志码
Cyclic Orbit Flag Codes
摘要:
在网络编码中,标志码是$\mathbb{F}_q^n$的嵌套子空间的序列的集合,是具有$q$元素的有限域$\mathbb{F}_q$。定义为作用于$\mathbb{F}_q^n$的标志的一般线性群的循环子群的轨道的标志码被称为循环轨道标志码。受arXiv:1403.1218中思想的启发,我们确定了循环轨道标志码的基数,并在标志的所有子空间都是向量空间(标志的最好朋友)的最大子域的帮助下提供了其距离的界限。特别注意的是两个特定的家庭的循环轨道标志码实现的极端可能的值的距离:伽罗瓦循环轨道标志码和最佳距离循环轨道标志码。我们详细研究这两类代码和分析的参数仍然有一个循环轨道结构的各自的子码。
英文摘要:
In network coding, a flag code is a set of sequences of nested subspaces of $\mathbb{F}_q^n$, being $\mathbb{F}_q$ the finite field with $q$ elements. Flag codes defined as orbits of a cyclic subgroup of the general linear group acting on flags of $\mathbb{F}_q^n$ are called cyclic orbit flag codes. Inspired by the ideas in arXiv:1403.1218, we determine the cardinality of a cyclic orbit flag code and provide bounds for its distance with the help of the largest subfield over which all the subspaces of a flag are vector spaces (the best friend of the flag). Special attention is paid to two specific families of cyclic orbit flag codes attaining the extreme possible values of the distance: Galois cyclic orbit flag codes and optimum distance cyclic orbit flag codes. We study in detail both classes of codes and analyze the parameters of the respective subcodes that still have a cyclic orbital structure.
