Let R be a commutative principal ideal domain, T : Mn(R) --\* Mm(R) an R-linear map which preserves idempotence. We determine the forms of T when n >/m and R ~ Fz, and solve some of Beasley's open problems. As a consequence, we prove that the set -~(R) of all R-linear maps on Mn(R) which preserve bo

We show that, over a principal ideal domain, the dynamic feedback equivalence for (not necessarily reachable) linear systems is reduced to the feedback equivalence for one-augmented systems. We also obtain the dynamic feedback classification for two-dimensional linear systems.
Let Z β R be a subgroup of the rationals and (S; β€) a ΓΏnite poset. In this paper we introduce the category Rep(S; R) of homogeneous completely decomposable groups H of type R with distinguished homogeneous completely decomposable subgroups H i (i β S) of the same type, respecting the order of S, i.e
Our aim in this paper is to improve on the algorithms for the computation of SAGBI and SAGBI-GrΓΆbner for subalgebras of polynomial rings in the special case where the base ring is a principal ideal domain. In addition we will show the existence in general of strong SAGBI bases (the natural analogue
