报告摘要：In this talk, building upon previous research, we utilize the defining-set approach to construct several classes of linear codes over Z4 by effectively using the properties of the trace function from GR(4,m) to Z4. As a result, we have been able to obtain new infinite families of linear codes over Z4 and completely determine their Lee weight distributions.
