Constacyclic codes%Torsion codes%Homogeneous distance
In this paper, the distribution of homogeneous distance of (1+u)-constacyclic codes over the of arbitrary lengths is studied. Firstly, the torsion codes of a (1+u)-constacyclic code over kR for a given length are introduced. Then, by using the torsion codes, a bound for the homogeneous distance of (1+u)-constacyclic codes over kR of any length is given. The exact homogeneous distance of some (1+u)-constacyclic codes over kR is also obtained.
