In this note, we generalize the concepts of minimal bases and maximal nonbases for integers, and prove some existence theorems for the generalized minimal bases and maximal nonbases, which generalize some results of Stiihr, Deza and Erdds, and Nathanson.
In this paper, continuing work of the second author (J. Pure Appl. Algebra 155 (2001) 77) for rational curves, we address the problem of computing the generators of the ideal of an irreducible parametric variety V to the computation of the generators of the ideal of a suitable ΓΏnite set of points on
