报告摘要：There are exactly 11 rings of order 4; four of which are unital by Rhagavandran(1969). Among the remaining seven we select three as alphabets for our codes: E,I,H. We study quasi self-dual codes and Type IV codes over these rings, two specialkinds of self-orthogonal codes. E is non-commutative and local, and leads to invarianttheory of weight enumerators. It is commutative local and leads to a massformula. H is commutative semi-local and allows classification under permutationequivalence. The build up construction is studied over E,I, and H. Joint workswith Adel Alahmadi, Amani Alkhatiry, Alaa Altassan, Widyan Bassafar, Alexis Bonnecaze,Hatoon Shoaib.
