內(nèi)容介紹：There are many metrics for linear codes, for example, for classical linear codes over finite rings or finite fields, the Hamming metric, Lee metric, RT metric; for subspace codes, rank metric and so on. MacWilliams identities respect to these codes were established. In this talk, I will introduce a new metric, the group-based metric for linear codes over finite rings or finite fields, I will present the MacWilliams identity for such metric. At the end of the talk, I will introduce some possible related research topics.
