Abstract (EN):
In this work we present some results on 2D behaviors described by linear constant coefficient partial difference equations where one of the independent variables, "time", is distinguished and plays a special role. We call such systems 'time-relevant'. We first give a test to check time-relevance starting from an arbitrary description of the behavior. Then, we introduce a stability notion for these systems and provide an algebraic test in terms of the location of the zeros of the determinant of a polynomial matrix describing the system. © 2011 IEEE.
