Let F_ p be a finite field, where p is an odd prime, and let u be an indeterminate. This article studies (1 − 2 u^ 2 )-constacyclic codes over the ring F_ p + u F_ p + u^ 2 F_ p , where u^ 3 = u . We describe generator polynomials of this kind of codes and investigate the structural properties of these codes by a decomposition theorem.
