โฆ Synopsis
The locally integrable function space L loc 1 is made a module over the ring of proper rational functions. Using this module structure, the notion of relative dimension is defined naturally for every linear subspace in (L loc 1 ) q . It is shown that the property of having finite relative dimension together with the property of having sufficiently many smooth trajectories and the evident property of differentiation-invariance characterize the weak solutions sets of linear constant coefficient differential systems among all linear subspaces.

Linear systems of an arbitrary number of inequalities provide external representations for the closed convex sets in the Euclidean space. In particular, the locally polyhedral systems introduced in this paper are the natural linear representation for quasipolyhedral sets (those subsets of the Euclid
