Query: Topics in asynchronous systems   In the paper we define and characterize the asynchronous systems from the
point of view of their autonomy, determinism, order, non-anticipation, time
invariance, symmetry, stability and other important properties. The study is
inspired by the models of the asynchronous circuits.
