Published in 2025 at "Bulletin of the Australian Mathematical Society"

DOI: 10.1017/s0004972725100567

Abstract: We study perfect codes in the homogeneous metric over the ring $\mathbb {Z}_{{2}^k}, k\ge 2$ . We derive arithmetic nonexistence results from Diophantine equations on the parameters resulting from the sphere packing conditions, and a… read more here.

Published in 2023 at "IEEE Transactions on Information Theory"

DOI: 10.1109/tit.2022.3213239

Abstract: Motivated by applications to DNA-storage, flash memory, and magnetic recording, we study perfect burst-correcting codes for the limited-magnitude error channel. These codes are lattices that tile the integer grid with the appropriate error ball. We… read more here.

Published in 2022 at "Problems of Information Transmission"

DOI: 10.1134/s0032946022010045

Abstract: A code is said to be propelinear if its automorphism group contains a subgroup acting on its codewords regularly. A subgroup of the group $$GA(r,q)$$ of affine transformations is said to be regular if it acts… read more here.

Published in 2024 at "Kragujevac Journal of Mathematics"

DOI: 10.46793/kgjmat2506.913t

Abstract: In this paper, we focus on the perfect and total perfect codes of the non-coprime and coprime graphs associated to the dihedral groups and finite Abelian groups. We used the advantage of independent sets and… read more here.
