Linear codes over the ring $Z_{4} + u Z_{4} + v Z_{4} + w Z_{4} + uv Z_{4} + u w Z_{4} + v w Z_{4} + uv w Z_{4}$

Bustomi, Aditya Purwa Santika, Djoko Suprijanto

We investigate linear codes over the ring $Z_{4} + u Z_{4} + v Z_{4} + w Z_{4} + uv Z_{4} + u w Z_{4} + v w Z_{4} + uv w Z_{4}$ , with…

Structure of linear codes over the ring $B_{k}$

Irwansyah, Djoko Suprijanto

We study the structure of linear codes over the ring $B_{k}$ which is defined by $F_{p^{r}} [v_{1}, v_{2}, \dots, v_{k}] / ⟨ v_{i}^{2} = v_{i}, v_{i} v_{j} = v_{j} v_{i} ⟩_{i, j = 1}^{k} .$ In order t…

On the strong non-rigidity of certain tight Euclidean designs

Eiichi Bannai, Etsuko Bannai, Djoko Suprijanto

We study the non-rigidity of Euclidean $t$ -designs, namely we study when Euclidean designs (in particular certain tight Euclidean designs) can be deformed keeping the property of b…

$Θ_{S} -$ cyclic codes over $A_{k}$

Irwansyah, Aleams Barra, Steven T. Dougherty +5

We study $Θ_{S} -$ cyclic codes over the family of rings $A_{k} .$ We characterize $Θ_{S} -$ cyclic codes in terms of their binary images. A family of Hermitian inner-products is defined and…

A Note on The Enumeration of Euclidean Self-Dual Skew-Cyclic Codes over Finite Fields

Irwansyah, Intan Muchtadi-Alamsyah, Ahmad Muchlis +2

In this paper we give the enumeration formulas for Euclidean self-dual skew-cyclic codes over finite fields when $(n, ∣ θ ∣) = 1$ and for some cases when $(n, ∣ θ ∣) > 1,$ where $n$ is the l…

Skew-Cyclic Codes over $B_{k}$

Irwansyah, Aleams Barra, Intan Muchtadi-Alamsyah +2

In this paper we study the structure of $θ$ -cyclic codes over the ring $B_{k}$ including its connection to quasi- $θ ~$ -cyclic codes over finite field $F_{p^{r}}$ and skew…
