G-algebras, twistings, and equivalences of graded categories [PDF]
, 2007 Given Z-graded rings A and B, we study when the categories gr-A and gr-B are equivalent. We relate the Morita-type results of Ahn-Marki and del Rio to the twisting systems introduced by Zhang.

The graded center of the stable category of a Brauer tree algebra [PDF]
, 2010 We calculate the graded center of the stable category of a Brauer tree algebra. The canonical map from the Tate analogue of Hochschild cohomology to the graded center of the stable category is shown to induce an isomorphism module taking quotients by ...

j -Multiplicity and depth of associated graded modules
Journal of Algebra, 2013 Let $R$ be a Noetherian local ring. We define the minimal $j$-multiplicity and almost minimal $j$-multiplicity of an arbitrary $R$-ideal on any finite $R$-module. For any ideal $I$ with minimal $j$-multiplicity or almost minimal $j$-multiplicity on a Cohen-Macaulay module $M$, we prove that under some residual assumptions, the associated graded module $

Artinian algebras and Jordan type
, 2020 The Jordan type of an element $\ell$ of the maximal ideal of an Artinian k-algebra A acting on an A-module M of k-dimension n, is the partition of n given by the Jordan block decomposition of the multiplication map $m_\ell$ on M.

Noncommutative Instantons and Twistor Transform [PDF]
, 2000 Recently N.Nekrasov and A.Schwarz proposed a modification of the ADHM construction of instantons which produces instantons on a noncommutative deformation of the 4-dimensional real affine space.

Multiplicities of graded components of local cohomology modules
Journal of Pure and Applied Algebra, 2005 Let \(M\) be a finitely generated graded module over a Noetherian homogeneous ring \(R\) with local base ring \((R_0,m_0).\) Let \(H^i_{R_+}(M)_n\) be the \(i\)-th local cohomology module of \(M\) with respect to the irrelevant ideal \(R_+\) of \(R.\) The authors study the multiplicity of \(H^i_{R_+}(M)_n\) relative to an \(m_0\)-primary ideal of \(R_0.

Classification of Graded Left-symmetric Algebra Structures on Witt and Virasoro Algebras
, 2007 We find that a compatible graded left-symmetric algebra structure on the Witt algebra induces an indecomposable module of the Witt algebra with 1-dimensional weight spaces by its left multiplication operators.

The Hodge theory of Soergel bimodules [PDF]
, 2014 We prove Soergel's conjecture on the characters of indecomposable Soergel bimodules. We deduce that Kazhdan-Lusztig polynomials have positive coefficients for arbitrary Coxeter systems.

A sub-functor for Ext and Cohen-Macaulay associated graded modules with bounded multiplicity [PDF]
Transactions of the American Mathematical Society, 2020 Let ( A , m ) (A,\mathfrak {m}) be a Cohen-Macaulay local ring and let C M ( A ) \mathrm {CM}(A) be the category of maximal Cohen-Macaulay A A -modules. We construct T :

On graded Jgr-2-absorbing primary submodule
Journal of Nigerian Society of Physical SciencesThis paper introduces the concept of graded Jgr-2-absorbing primary submodules, a new intermediate structure in graded module theory. Motivated by the need to extend and unify classical notions such as graded prime and graded primary submodules, the ...
