Query: KW-models for (multivariate) linear differential systems   A class of state models, called Kronecker-Weierstrass models (or, simply,
KW-models), is introduced, and the state representation problem for linear
differential systems is studied in the context of these models. It is shown, in
particular, that there is a canonical one-to-one correspondence between linear
differential systems and similarity classes of minimal proper KW-models.
