Abstract :
The equations characterizing a systems problem may be expressed as a network of directed branches. (The block diagram of a servomechanism is a familiar example.) A study of the topological properties of such graphs leads to techniques which have proven useful, both for the discussion of the general theory of feedback and for the solution of practical analysis problems.
