In this work, we study a new family of rings, \({\mathscr{B}}_{j,k}\), whose base field is the finite field \({\mathbb {F}}_{p^{r}}\). We study the structure of this family of rings and show that each member of the family is a commutative Frobenius ring. We define a Gray map for the new family of rings, study G-codes, self-dual G-codes, and reversible G-codes over this family. In particular, we show that the projection of a G-code over \({\mathscr{B}}_{j,k}\) to a code over \({\mathscr{B}}_{l,m}\) is also a G-code and the image under the Gray map of a self-dual G-code is also a self-dual G-code when the characteristic of the base field is 2. Moreover, we show that the image of a reversible G-code under the Gray map is also a reversible \(G^{2^{j+k}}\)-code. The Gray images of these codes are shown to have a rich automorphism group which arises from the algebraic structure of the rings and the groups. Finally, we show that quasi-G codes, which are the images of G-codes under the Gray map, are also Gs-codes for some s.

环B j,k $ {\ mathscr {B}} _ {j,k} $上的G代码,自对偶G代码和可逆G代码
在这项工作中,我们研究了一个新的环族\({\ mathscr {B}} _ {j,k} \),其基本字段是有限字段\({\ mathbb {F}} _ {p ^ {r}} \)。我们研究了该环族的结构,并表明该族的每个成员都是可交换的Frobenius环。我们为新的戒指族定义了一个灰色图,研究该族的G代码,自对偶G代码和可逆G代码。特别是,我们证明了G代码在\({\ mathscr {B}} _ {j,k} \)上的投影到代码在\({\ mathscr {B}} _ {l,m}上的投影\)也是G代码,并且是自对偶G的Gray映射下的图像基字段的特征为2时,-code也是自对偶G - code。此外,我们证明了Gray映射下可逆G- code的图像也是可逆\(G ^ {2 ^ { j + k}} \) -代码。这些代码的格雷图像显示具有丰富的自同构群,该自同构群是由环和群的代数结构引起的。最后,我们表明,准摹代码,这是的图像摹灰色地图下-codes,也摹小号一些-codes小号。
