Abstract
Let F2m be a finite field of cardinality 2m, R=F2m[u]âãu4ã and n be an odd positive integer. For any δ,αâF2mÃ, ideals of the ring R[x]âãx2nâ(δ+αu2)ã are identified as (δ+αu2)-constacyclic codes of length 2n over R. In this paper, an explicit representation and enumeration for all distinct (δ+αu2)-constacyclic codes of length 2n over R are presented.
