ABSTRACT The question of whether a polynomial belongs to a finitely generated differential ideal remains open. This problem is solved
only in some particular cases. In the paper, we propose a method, which reduces the test of membership for fractional ideals
generated by a composition of differential polynomials to another, simpler, membership problem.

ABSTRACT: We generalize Hoon Hong’s theorem on Gröbner bases under composition to the case of differential standard bases in the ordinary ring of differential polynomials {ie4152-01}. In particular, we prove that some ideals have finite differential standard bases. We construct special orderings on differential monomials such that ideals generated by some power of a quasi-linear polynomial acquire finite differential standard bases.
