Annotation | The algebraic and geometric properties of the sum of cyclic subspaces with respect to a linear operator, which arise in the study of linear control systems, are investigated. The resulting properties are expressed in terms of minimal annihilating polynomials of the sum and intersection of the corresponding cyclic subspaces. The canonical forms of the linear operator are considered both in partially consistent bases of subspaces and in the cyclic basis of the sum of these subspaces. |

Keywords | linear operator, cyclic subspace, minimal annihilating polynomial. |
