Crossed products of 4-algebras. Applications

期刊: JOURNAL OF ALGEBRA, 2023; 614 ()

A 4-algebra is a commutative algebra A over a field k such that (a(2))(2) = 0, for all a is an element of A. We have proved recently [22] that 4-algeb......

Descent of equivalences for blocks with Klein four defect groups

期刊: JOURNAL OF ALGEBRA, 2023; 614 ()

We show that the splendid Rickard complexes for blocks with Klein four defect groups constructed by Rickard and Linckelmann descend to non splitting c......

Hammocks to visualize the support of finitely presented functors

期刊: JOURNAL OF ALGEBRA, 2023; 616 ()

Many properties of a module can be expressed in terms of the dimension of the vector space obtained by applying a finitely presented functor to that m......

Some criteria for stably birational equivalence of quadratic forms

期刊: JOURNAL OF ALGEBRA, 2023; 616 ()

Let cp and 0 be quadratic forms over a field K of characteristic different from 2. In this paper, we give a criterion for isotropy of cp over the func......

Lower defect groups and vertices of simple modules

期刊: JOURNAL OF ALGEBRA, 2023; 617 ()

We compare lower defect groups associated with Irregular classes and vertices of simple modules for a block of a finite group algebra. We show that th......

Formulae of ?-divided powers in Uq(sl2), III

期刊: JOURNAL OF ALGEBRA, 2023; 619 ()

The z -divided powers (depending on a parity) form the zcanonical basis for the split rank 1 zquantum group and they are a basic ingredient for zquant......

The essential p-dimension of the split finite quasi-simple groups of classical Lie type

期刊: JOURNAL OF ALGEBRA, 2023; 620 ()

In this paper, we compute the essential p-dimension of the split finite quasi-simple groups of classical Lie type at the defining prime, specifically ......

Singular equivalences and Auslander-Reiten conjecture

期刊: JOURNAL OF ALGEBRA, 2023; 623 ()

Auslander-Reiten conjecture, which says that an Artin algebra does not have any non-projective generator with vanishing self-extensions in all positiv......

Arithmetic jet spaces

期刊: JOURNAL OF ALGEBRA, 2023; 623 ()

One of the primary objectives of this paper is to establish compatibility between two different jet space functors in the most general context. We fir......

Euler-symmetric complete intersections in projective space

期刊: JOURNAL OF ALGEBRA, 2023; 624 ()

Euler-symmetric projective varieties, introduced by Baohua Fu and Jun-Muk Hwang in 2020, are nondegenerate projective varieties admitting many Cx-acti......

Powers with minimal commutator length in free products of groups

期刊: JOURNAL OF ALGEBRA, 2023; 629 ()

Given a free product of groups G = *j is an element of JAj and a natural number n, what is the minimal possible commutator length of an element gn is ......

Geometry of points satisfying Cayley-Bacharach conditions and applications

期刊: JOURNAL OF ALGEBRA, 2023; 631 ()

In this paper, we study the geometry of points in complex projective space that satisfy the Cayley-Bacharach condition with respect to the complete li......

The structure of quasi-complete intersection ideals ✩

期刊: JOURNAL OF ALGEBRA, 2023; 632 ()

We prove that every quasi-complete intersection (q.c.i.) ideal is obtained from a pair of nested complete intersection ideals by way of a flat base ch......

Level and pseudo-Gorenstein binomial edge ideals

期刊: JOURNAL OF ALGEBRA, 2023; 632 ()

We prove that level binomial edge ideals with regularity 2 and pseudo-Gorenstein binomial edge ideals with regularity 3 are cones, and we describe the......

On the dimension of dual modules of local cohomology and the Serre's condition for the unmixed Stanley-Reisner ideals of small height

期刊: JOURNAL OF ALGEBRA, 2023; 632 ()

In this paper, we focus on the dimension of dual modules of local cohomology of Stanley-Reisner rings to obtain a new vector. This vector contains imp......
