The students will be provided with the principles of the algebraic theory of discrete linear control. The basic algebraic concepts and methods used in the theory will be discussed. The main interest will be focused on the study of polynomials, because they are the most important tools of the theory of discrete linear control. First, the fundamentals of the theory of rings and the theory of formal series will be expounded. This will be followed by the study of polynomials (as special cases of formal series) and polynomial matrices from the view-point of the theory of discrete linear control. This will be done with the help of the
fundamental knowledge of the theory of rings.
