Title: Translation Association Schemes, Poset Metrics, And The Shape Enumerator Of Codes
Author: Barg A.
Firer M.
Abstract: Poset metrics form a generalization of the Hamming metric on the space double-struck F q n. Orbits of the group of linear isometries of the space give rise to a translation association scheme. The structure of the dual scheme is important in studying duality of linear codes; this study is facilitated if the scheme is self-dual. We study the relation between self-duality of the scheme and that of the poset. We also give new examples of poset metric spaces and describe the association schemes that arise from linear isometries. © 2012 IEEE.
