The behavioral theory for systems described by a set of linear constant coefficient partial differential equations has been a challenging and fruitful area of research for quite some time (see, for instance, Pillai and Shankar , Oberst  and Wood et al. ). An excellent elementary introduction to the behavioral theory in the 1-D case (corresponding to systems described by ...
