Classification of self-dual cyclic codes over the chain ring $$\mathbb Z_p[u]/\langle u^3 \rangle $$

Determination for minimum symbol-pair and RT weights via torsional degrees of repeated-root cyclic codes

“…For many years, linear codes have active developments over various rings [9,10,11,12,13,14,17,21,23]. Recently, finding symbol-pair weight and RT weight is a great challenge in coding theory [5,16,22].…”
