  • On Countably Generated Dimension

      Authors: Maryam Davoudian
      Pages: 361 - 366
      Abstract: Algebra Colloquium, Volume 28, Issue 03, Page 361-366, September 2021.
      In this article, we introduce and study the concept of countably generated dimension, which is a Krull-like dimension extension of the concept of DCC on countably generated submodules. We show that some of the basic results of Krull dimension are true for countably generated dimension. It is shown that an [math]-module [math] has Krull dimension if and only if it has countably generated dimension, and its Krull dimension and countably generated dimension coincide.

  • Nil-Clean Rings with Involution

      Authors: Jian Cui, Guoli Xia, Yiqiang Zhou
      Pages: 367 - 378
      Abstract: Algebra Colloquium, Volume 28, Issue 03, Page 367-378, September 2021.
      A [math]-ring [math] is called a nil [math]-clean ring if every element of [math] is a sum of a projection and a nilpotent. Nil [math]-clean rings are the [math]-version of nil-clean rings introduced by Diesl. This paper is about the nil [math]-clean property of rings with emphasis on matrix rings. We show that a [math]-ring [math] is nil [math]-clean if and only if [math] is nil and [math] is nil [math]-clean. For a 2-primal [math]-ring [math], with the induced involution given by[math], the nil [math]-clean property of [math] is completely reduced to that of [math]. Consequently, [math] is not a nil [math]-clean ring for [math], and [math] is a nil [math]-clean ring if and only if [math] is nil, [math]is a Boolean ring and [math] for all [math].

  • Schubert Class and Cyclotomic NilHecke Algebras

      Authors: Kai Zhou, Jun Hu
      Pages: 379 - 398
      Abstract: Algebra Colloquium, Volume 28, Issue 03, Page 379-398, September 2021.
      Let [math] and [math] be positive integers such that [math], and let [math] be the Grassmannian which consists of the set of [math]-dimensional subspaces of [math]. There is a [math]-graded algebra isomorphism between the cohomology [math] of [math] and a natural [math]-form [math] of the [math]-graded basic algebra of the type [math] cyclotomic nilHecke algebra [math]. We show that the isomorphism can be chosen such that the image of each (geometrically defined) Schubert class [math] coincides with the basis element [math] constructed by Hu and Liang by purely algebraic method, where [math] with [math] for each [math], and [math] is the [math]-multipartition of [math] associated to [math]. A similar correspondence between the Schubert class basis of the cohomology of the Grassmannian [math] and the [math]'s basis ([math] is an [math]-multipartition of [math] with each component being either [math] or empty) of the natural [math]-form [math] of the [math]-graded basic algebra of [math] is also obtained. As an application, we obtain a second version of the Giambelli formula for Schubert classes.

  • A Construction of Sequentially Cohen–Macaulay Graphs

      Authors: Aming Liu, Tongsuo Wu
      Pages: 399 - 414
      Abstract: Algebra Colloquium, Volume 28, Issue 03, Page 399-414, September 2021.
      For every simple graph [math], a class of multiple clique cluster-whiskered graphs [math] is introduced, and it is shown that all such graphs are vertex decomposable; thus, the independence simplicial complex [math] is sequentially Cohen–Macaulay. The properties of the graphs [math] and [math] constructed by Cook and Nagel are studied, including the enumeration of facets of the complex [math] and the calculation of Betti numbers of the cover ideal [math]. We also prove that the complex[math] is strongly shellable and pure for either a Boolean graph [math] or the full clique-whiskered graph [math] of [math], which is obtained by adding a whisker to each vertex of [math]. This implies that both the facet ideal [math] and the cover ideal [math] have linear quotients.

      We provide the regularity and the Cohen–Macaulay type of binomial edge ideals of Cohen–Macaulay cones, and we show the extremal Betti numbers of some classes of Cohen–Macaulay binomial edge ideals: Cohen–Macaulay bipartite and fan graphs. In addition, we compute the Hilbert–Poincaré series of the binomial edge ideals of some Cohen–Macaulay bipartite graphs.

      A finite group is said to be weakly separable if every algebraic isomorphism between two [math]-ringsover this group is induced by a combinatorial isomorphism. We prove that every abelian weakly separable group only belongs to one of several explicitly given families.

  • Links Between [math]-Groups and Hypergroups

      Authors: Irina Cristea, Michal Novák, Babatunde Oluwaseun Onasanya
      Pages: 441 - 452
      Abstract: Algebra Colloquium, Volume 28, Issue 03, Page 441-452, September 2021.
      The concept of an [math]-group is an upgrade of the concept of a group, in which a new operation is defined on the family of non-empty subsets of a group. If this new support set together with the new operation is a group, then we call it an [math]-group. On the other hand, a hyperoperation is a mapping having the same codomain as the operation of an [math]-group, i.e., the family of non-empty subsets of the initial set, but a different domain — the set itself. This could be (and was indeed) a source of confusion, which is clarified in this paper. Moreover, [math]-groups naturally lead to constructions of hypergroups. The links between these two algebraic concepts are presented, with the aim of reviving the old notion of an [math]-group in the current research on algebraic hyperstructures. One of such existing links and one newly established link are also discussed.

      Abstract: Algebra Colloquium, Volume 28, Issue 03, Page 453-468, September 2021.
      This article concerns a ring property called pseudo-reduced-over-center that is satisfied by free algebras over commutative reduced rings. The properties of radicals of pseudo-reduced-over-center rings are investigated, especially related to polynomial rings. It is proved that for pseudo-reduced-over-center rings of nonzero characteristic, the centers and the pseudo-reduced-over-center property are preserved through factor rings modulo nil ideals. For a locally finite ring [math], it is proved that if [math] is pseudo-reduced-over-center, then [math] is commutative and [math] is a commutative regular ring with [math] nil, where [math] is the Jacobson radical of [math].

      For a partition [math] and a prime [math], we prove a necessary and sufficient condition for there to exist a composition [math] such that [math] can be obtained from [math] after rearrangement and no partial sums of [math] are divisible by [math]. To demonstrate why we are interested in the question, we compute some signed [math]-Kostka numbers.

      Let [math] be the underlying base field of characteristic [math] and denote by [math] the even part of the finite-dimensional Lie superalgebra [math]. We give the generator sets of the Lie algebra [math]. Using certain properties of the canonical tori of [math], we describe explicitly the derivation algebra of [math].

      Let [math], [math] and [math] be integers with [math]. The set-inclusion graph [math] is the graph whose vertex set consists of all [math]- and [math]-subsets of [math], where two distinct vertices are adjacent if one of them is contained in the other. In this paper, we determine the spectrum and automorphism group of [math].

      Let [math] be a Morita ring which is an Artin algebra. In this paper we investigate the relations between the Gorenstein-projective modules over a Morita ring [math] and the algebras [math] and [math]. We prove that if [math] is a Gorenstein algebra and both [math] and [math] (resp., both [math] and [math]) have finite projective dimension, then [math] (resp., [math]) is a Gorenstein algebra. We also discuss when the CM-freeness and the CM-finiteness of a Morita ring [math] is inherited by the algebras [math] and [math].

      Let [math] be a commutative ring and [math] be its zero-divisor graph. We completely determine the structure of all finite commutative rings whose zero-divisor graphs have clique number one, two, or three. Furthermore, if [math] (each [math] is local for [math]), we also give algebraic characterizations of the ring [math] when the clique number of [math] is four.
