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 $${\displaystyle R_{i}R_{j}\subseteq R_{i+j}}$$. The index set is usually the set of nonnegative integers or the set of integers, but can be any … See more Generally, the index set of a graded ring is assumed to be the set of nonnegative integers, unless otherwise explicitly specified.

WebMar 24, 2024 · Cohomology is an invariant of a topological space, formally "dual" to homology, and so it detects "holes" in a space. Cohomology has more algebraic structure than homology, making it into a graded ring (with multiplication given by the so-called "cup product"), whereas homology is just a graded Abelian group invariant of a space. A … WebMar 6, 2024 · The grading on the polynomial ring S = A [ x 0, …, x n] is defined by letting each x i have degree one and every element of A, degree zero. Comparing this to the definition of O ( 1), above, we see that the sections of O ( 1) are in fact linear homogeneous polynomials, generated by the x i themselves.
