Graded ideal
WebAn ideal that satis es the equivalent conditions in the above exercise is a homoge-neous (or graded) ideal. Note that if Iis a homogeneous ideal in a graded ring R, then the quotient ring R=Ibecomes a graded ring in a natural way: R=I= M m2Z R m=(I\R m): We now return to the study of Pn. The starting observation is that while it does WebLet be a graded ideal, and let . The following hold: (a) If is a homogeneous minimal generating set of , then: (b) ; (c) with equality if ; (d) If I has no embedded primes, then The formulas of Parts (a) and (b) give an algorithm to compute the v-number using Macaulay 2 [ 2] (Example 1, Procedure A1 in Appendix A ).

Given a graded module M over a commutative graded ring R, one can associate the formal power series $${\displaystyle P(M,t)\in \mathbb {Z} [\![t]\!]}$$: $${\displaystyle P(M,t)=\sum \ell (M_{n})t^{n}}$$ (assuming $${\displaystyle \ell (M_{n})}$$ are finite.) It is called the Hilbert–Poincaré series of M. A graded module is … See more In mathematics, in particular abstract algebra, a graded ring is a ring such that the underlying additive group is a direct sum of abelian groups $${\displaystyle R_{i}}$$ such that A graded module is … See more The corresponding idea in module theory is that of a graded module, namely a left module M over a graded ring R such that also $${\displaystyle M=\bigoplus _{i\in \mathbb {N} }M_{i},}$$ and See more Intuitively, a graded monoid is the subset of a graded ring, $${\displaystyle \bigoplus _{n\in \mathbb {N} _{0}}R_{n}}$$, generated by the $${\displaystyle R_{n}}$$'s, without using the additive part. That is, the set of elements of the graded monoid is See more Generally, the index set of a graded ring is assumed to be the set of nonnegative integers, unless otherwise explicitly specified. This is the case in this article. A graded ring is a ring that is decomposed into a direct sum See more The above definitions have been generalized to rings graded using any monoid G as an index set.
