我们考虑的概念(q,m)-polymatoid,由于Shiromoto,和更一般的概念(q,m)-n-polymatoid,并显示如何广义的重量可以为他们定义。此外,我们建立了一个对偶这些重量类似魏对偶的广义汉明重量的线性码。作为结果,得到了Ravagnani关于Delsarte秩度量码的相应结果,以及Martínez-Peñas和松本关于相对广义秩权的相应结果.
We consider the notion of a (q,m)-polymatroid, due to Shiromoto, and the more general notion of (q,m)-demi-polymatroid, and show how generalized weights can be defined for them. Further, we establish a duality for these weights analogous to Wei duality for generalized Hamming weights of linear codes. The corresponding results of Ravagnani for Delsarte rank metric codes, and Martínez-Peñas and Matsumoto for relative generalized rank weights are derived as a consequence.
