Abstract
A new set of integer invariants of a discrete time nonlinear system is introduced. Following the linear and continuous time nonlinear theory, this set is called the structure at infinity of the system. These integers contain structural information about the system. To support this idea the general block decoupling problem and a special case of the noninteracting control problem are solved in terms of the zeros at infinity.
