Duality of Codes over Non-unital Rings of Order Four


In this paper, we present a basic theory of the duality of linear codes over three of the non-unital rings of order four; namely I, E , and H as denoted in (Fine, 1993). A new notion of duality is introduced in the case of the non-commutative ring E . The notion of self-dual codes with respect to this duality coincides with that of quasi self-dual codes over E as introduced in (Alahmadi et al , 2022). We characterize self-dual codes and LCD codes over the three rings, and investigate the properties of their corresponding additive codes over F 4 . We study the connection between the dual of any linear code over these rings and the dual of its associated binary codes. A MacWilliams formula is established for linear codes over E .
