线性码的2-设计和3-设计的无限族

Infinite families of 2-designs and 3-designs from linear codes

Cunsheng Ding, Chengju Li

摘要:

编码理论和$t$设计之间的相互作用开始于许多年前。虽然每个$t$ -设计都会在每个有限域上产生线性代码,但直接从线性或非线性代码导出无限族$t$ -设计的最大$t$是$t=3$。从某些参数的线性码中导出了零星$4$ -设计和$5$ -设计.本文的主要目的是从线性码中构造许多无限族的$2$ -设计和$3$ -设计.一些已知的$t$ -设计的参数也被导出。此外,还给出了许多$2$ -设计的有限族.

英文摘要:

The interplay between coding theory and $t$-designs started many years ago. While every $t$-design yields a linear code over every finite field, the largest $t$ for which an infinite family of $t$-designs is derived directly from a linear or nonlinear code is $t=3$. Sporadic $4$-designs and $5$-designs were derived from some linear codes of certain parameters. The major objective of this paper is to construct many infinite families of $2$-designs and $3$-designs from linear codes. The parameters of some known $t$-designs are also derived. In addition, many conjectured infinite families of $2$-designs are also presented.
