Repeated-Root Constacyclic Codes of Length over the Finite Non-Chain Ring and their Duals
Divya Acharya, Prasanna Poojary, Vadiraja Bhatta G R
This study aims to determine the algebraic structures of -constacyclic codes of length over the finite commutative non-chain ring $\mathcal{R}=\frac{\mathbb{F}_{p^m}[u, v…
