報告摘要：Codes with symbols over the ring of integers over the quaternary alphabet Z4 = {0,1,2,3} have played an important role in solving old problems in coding theory as well as in constructing new and optimal codes. Codes over Z4 have also demonstrated their importance by being applied to construct excellent classes of sequences that are used in international mobile communication standards. Codes over Z4 have also many interesting connections in many areas in mathematics including combinatorial t-designs.This talk will give a brief introduction to codes over Z4 and review some results on codes, sequences and t-designs that are constructed from codes over Z4. Some related open research problems will be discussed.
