An algorithm is described which computes generators of the kernel of derivations on k[X₁,...,Xₙ] up to a previously given bound. For w-homogeneous derivations it is shown that if the algorithm computes a generating set for the kernel then this set is minimal.

We study when the modifications of the Cohen-Macaulay vertex cover ideal of a graph are Cohen-Macaulay.

Recently, motivated by Anderson, Dumitrescu’s -finiteness, D. Bennis, M. El Hajoui (2018) introduced the notion of -coherent rings, which is the -version of coherent rings. Let be a commutative ring with unity graded by an arbitrary commutative monoid , and a multiplicatively closed subset of nonzero homogeneous elements of . We define to be graded--coherent ring if every finitely generated homogeneous ideal of is -finitely presented. The purpose of this paper is to give the graded...

Let be a group with identity and let be a -graded ring. In this paper, we introduce and study the concept of graded -ideals of . A proper graded ideal of is called a graded -ideal of if whenever where , then either or or . We introduce several results concerning --ideals. For example, we give a characterization of graded -ideals and their homogeneous components. Also, the relations between graded -ideals and others that already exist, namely, the graded prime ideals,...

We describe a collection of differential graded rings that categorify weight spaces of the positive half of the quantized universal enveloping algebra of the Lie superalgebra 𝔤𝔩(1|2).

Let k be a field, let be a finite group. We describe linear -gradings of the polynomial algebra k[x 1, ..., x m] such that the unit component is a polynomial k-algebra.

The class of loop spaces of which the mod cohomology is Noetherian is much larger than the class of -compact groups (for which the mod cohomology is required to be finite). It contains Eilenberg–Mac Lane spaces such as and 3-connected covers of compact Lie groups. We study the cohomology of the classifying space of such an object and prove it is as small as expected, that is, comparable to that of . We also show that X differs basically from the classifying space of a -compact group...
