Query: Cyclic codes over some special rings   In this paper we will study cyclic codes over some special rings:
F_{q}[u]/(u^{i}), F_{q}[u_1,...u_{i}]/(u_1^2,u_2^2,...,u_{i}^2, u_1 u_2 - u_2
u_1,...,u_{i}u_{j} - u_{j}u_{i},...), F_{q}[u,v]/(u^{i},v^{j},uv-vu), q=p^{r},
where p is a prime number, r\in N-{0} and F_{q} is a field with q elements.
