The Hilbert Coefficients of the Fiber Cone and the a-Invariant of the Associated Graded Ring [PDF]
Canadian Journal of Mathematics - Journal Canadien de Mathematiques, 2006 Let $(A,\mathfrak{m})$ be a Noetherian local ring with infinite residue field and let $I$ be an ideal in $A$ and let $F(I)={{\oplus }_{n\ge 0}}{{I}^{n}}/\mathfrak{m}{{I}^{n}}$ be the fiber cone of $I$ .

Computing nilpotent quotients in finitely presented Lie rings [PDF]
Discrete Mathematics & Theoretical Computer Science, 1997 A nilpotent quotient algorithm for finitely presented Lie rings over Z (and Q) is described. The paper studies the graded and non-graded cases separately.

Parabolic-Index Ring-Core Fiber Supporting High-Purity Orbital Angular Momentum Modes
Sensors, 2023 We design a graded-index ring-core fiber with a GeO2-doped silica ring core and SiO2 cladding. This fiber structure can inhibit the effect of spin-orbit coupling to mitigate the power transfer among different modes and eventually enhance the orbital ...

Three-Dimensional Manifolds, Skew-Gorenstein Rings and their Cohomology [PDF]
, 2010 Graded skew-commutative rings occur often in practice. Here are two examples: 1) The cohomology ring of a compact three-dimensional manifold. 2) The cohomology ring of the complement of a hyperplane arrangement (the Orlik-Solomon algebra).

On the union of graded prime ideals
Open Physics, 2016 In this paper we investigate graded compactly packed rings, which is defined as; if any graded ideal I of R is contained in the union of a family of graded prime ideals of R, then I is actually contained in one of the graded prime ideals of the family ...

The Cohen-Macaulay representation type of arithmetically Cohen-Macaulay varieties [PDF]
Épijournal de Géométrie Algébrique, 2021 We show that all reduced closed subschemes of projective space that have a Cohen-Macaulay graded coordinate ring are of wild Cohen-Macaulay type, except for a few cases which we completely classify.

On the Algebraic Classification of Module Spectra [PDF]
, 2011 Using methods developed by Franke, we obtain algebraic classification results for modules over certain symmetric ring spectra ($S$-algebras). In particular, for any symmetric ring spectrum $R$ whose graded homotopy ring $\pi_*R$ has graded global ...

Leavitt path algebras: Graded direct-finiteness and graded $\Sigma$-injective simple modules
, 2017 In this paper, we give a complete characterization of Leavitt path algebras which are graded $\Sigma $-$V$ rings, that is, rings over which a direct sum of arbitrary copies of any graded simple module is graded injective.

The graded ring of quantum theta functions for noncommutative torus with real multiplication [PDF]
, 2006 For the quantum torus generated by unitaries UV = e(θ)V U there exist nontrivial strong Morita autoequivalences in the case when θ is a real quadratic irrationality. A.Polishchuk introduced and studied the graded ring of holomorphic sections of powers of
