Identifying cyclic and (1 + 2v)-constacyclic codes over Z?[v]/ <v³ – 1> with Z?-linear codes
Kom, St Timothy; Ratnabala Devi, Okram (Işık University Press, 2023-07)This paper studies cyclic and (1 + 2v)-constacyclic codes over the ring Z?[v]/<v³ – 1>. By introducing three different Gray maps, we show that the Gray images of cyclic codes are quasi-cyclic codes over Z? and that of (1 ... -
On a class of constacyclic codes over the ring Z4[u]/< u² − 3 >
Thoudam, Dolly; Ratnabala Devi, Okram (Işık University Press, 2025-04-01)In this paper, λ-constacyclic codes and skew-λ-constacyclic codes over the ring R = Z4[u]/< u² − 3 > are studied for λ = 3 and 2 + 3u. Introducing new Gray maps from R to the copies of Z4, we observed that Gray images of ...
