Stillness in Nature: Eeo Stubblefield’s acted to the univariate dimension polynomials associated with subsets of ℕ., because the problem of determination of such polynomials is a part of the problem of computing Kolchin’s differential dimension polynomial of finitely generated differential field extensions.
