The strong nil-cleanness of semigroup rings
Open Mathematics, 2020 In this paper, we study the strong nil-cleanness of certain classes of semigroup rings. For a completely 0-simple semigroup M=ℳ0(G;I,Λ;P)M={ {\mathcal M} }^{0}(G;I,\text{Λ};P), we show that the contracted semigroup ring R0[M]{R}_{0}{[}M] is ...

A generalization of Kruskal–Katona’s theorem
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 Let K be a field, E the exterior algebra of a finite dimensional K-vector space, and F a finitely generated graded free E-module with homogeneous basis g1, . . ., gr such that deg g1 ≤ deg g2 ≤ · · · ≤ deg gr.

Hilbert series and applications to graded rings
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 7, Page 397-403, 2003., 2003 This paper contains a number of practical remarks on Hilbert series that we expect to be useful in various contexts. We use the fractional Riemann‐Roch formula of Fletcher and Reid to write out explicit formulas for the Hilbert series P(t) in a number of cases of interest for singular surfaces (see Lemma 2.1) and 3‐folds. If X is a ℚ‐Fano 3‐fold and S ∈

Some properties of graded comultiplication modules
Open Mathematics, 2017 Let G be a group with identity e. Let R be a G-graded commutative ring and M a graded R-module. In this paper we will obtain some results concerning the graded comultiplication modules over a commutative graded ring.

Notes on the Graded Radical of Graded Submodules [PDF]
, 2011 Let G be a group with identity e, and let R be a G-graded commutative ring, and let M be a graded R-module. In general, the graded radical of a graded primary submodule is not graded prime.

On the Structure of A 0 in Graded Principal Ideal Domains [PDF]
, 2012 In Caenepeel and Oystaeyen's [3] discussion of Bauer groups and the cohomology of graded rings, the topic of commutative rings arises. Specifically, certain results arise regarding graded principal ideal domains and graded Dedekind domains.

Joint Implementation in Climate Change Policy [PDF]
The textbook economists' model of a tradable permit system cannot usually be applied perfectly at either the domestic or international scale because of the difficulty and/or expense of defining allocations to and monitoring emissions of some groups, as ...
