本文的目的是从几何的观点发展有限链环上的线性码理论。推广了域上线性码的一个著名结果,证明了在射影Hjelmslev几何中,链环上的所谓胖线性码与点的多集之间存在一一对应关系,即半线性同构码对应于等价的多集,反之亦然.使用选定的一类多集,我们表明,某些麦克唐纳码是线性表示的非平凡链环。
The aim of this paper is to develop a theory of linear codes over finite chain rings from a geometric viewpoint. Generalizing a well-known result for linear codes over fields, we prove that there exists a one-to-one correspondence between so-called fat linear codes over chain rings and multisets of points in projective Hjelmslev geometries, in the sense that semilinearly isomorphic codes correspond to equivalent multisets and vice versa. Using a selected class of multisets we show that certain MacDonald codes are linearly representable over nontrivial chain rings.
