Partially lossy queue monoids (plq monoids) model the behavior of queues that can non-deterministically forget specified parts of their content at any time. We call the subsets of this monoid partially lossy queue languages (plq languages). While many decision problems on recognizable plq languages are decidable, most of them are undecidable if the languages are rational. In particular, in this monoid the classes of rational and recognizable languages do not coincide. This is due to the fact that the class of recognizable plq languages is not closed under multiplication and iteration. However, we can generate the recognizable plq languages using special rational expressions consisting of the Boolean operations and restricted versions of multiplication and iteration. From these special rational expressions we can also obtain an MSO logic describing the recognizable plq languages. Moreover, we provide similar results for the class of aperiodic languages in the plq monoid.
部分有损队列monoids (plq monoids)对任何时候都可能不确定地忘记其内容的指定部分的队列行为进行建模。我们称这种一元群的子集为部分有损队列语言(plq语言)。虽然许多可识别plq语言的决策问题是可确定的,但如果语言是理性的,大多数决策问题是不可确定的。特别地,在这个单群中,理性语言和可识别语言的类别并不重合。这是由于可识别的plq语言类在乘法和迭代下不是封闭的。然而,我们可以使用由布尔运算和限制版本的乘法和迭代组成的特殊理性表达式生成可识别的plq语言。从这些特殊的有理表达式中,我们还可以得到描述可识别的plq语言的MSO逻辑。此外,我们对plq单群中的非周期语言类也给出了类似的结果。

Let the product of points [Formula: see text] and [Formula: see text] be the vertex [Formula: see text] of the right isosceles triangle for which [Formula: see text] is the base, and [Formula: see text] is oriented anticlockwise. This yields a quasigroup that satisfies laws [Formula: see text], [Formula: see text] and [Formula: see text]. Such quasigroups are called quadratical. Quasigroups that satisfy only the latter two laws are equivalent to perfect Mendelsohn designs of length four ([Formula: see text]). This paper examines various algebraic identities induced by [Formula: see text], classifies finite quadratical quasigroups, and shows how the square structure of quadratical quasigroups is associated with toroidal grids.
设[公式:见文]与[公式:见文]之积为以[公式:见文]为底的直角等腰三角形的顶点[公式:见文],且[公式:见文]为逆时针方向。这就产生了一个满足定律[公式:见文]、[公式:见文]和[公式:见文]的拟群。这样的拟群称为二次群。只满足后两个定律的拟群等价于长度为4的完美门德尔松设计(公式:见原文)。本文研究了由[公式:见文]导出的各种代数恒等式,对有限二次拟群进行了分类,并说明了二次拟群的方形结构如何与环面网格相关联。

On the commutator in Leibniz algebras 莱布尼兹代数中的对易子
Pub Date : 2022-02-21 DOI: 10.1142/s0218196722500333

We prove that the class of algebras embeddable into Leibniz algebras with respect to the commutator product is not a variety. It is shown that every commutative metabelain algebra is embeddable into Leibniz algebras with respect to the anti-commutator. Furthermore, we study polynomial identities satisfied by the commutator in every Leibniz algebra. We extend the result of Dzhumadil’daev in [A. S. Dzhumadil’daev, [Formula: see text]-Leibniz algebras, Serdica Math. J. 34(2) (2008) 415–440]. to identities up to degree 7 and give a conjecture on identities of higher degrees. As a consequence, we obtain an example of a non-Spechtian variety of anticommutative algebras.

On conormal subgroups 关于正规子群

We introduce the concept of a conormal subgroup: a subgroup is conormal if it is contranormal in its normal closure. This unifies the concepts of normal and contranormal subgroups. We obtain some important properties of conormal subgroups, describe their connections with transitivity of normality, and study groups in which all conormal subgroups are normal.
我们引入了正规子群的概念:如果子群的正规闭包是正规的,那么子群就是正规的。这统一了正规子群和异正规子群的概念。我们得到了正规子群的一些重要性质,描述了它们与正规可传递性的联系,以及所有正规子群都是正规的学习群。

Let $G$ be a finite group and $p$ a fixed prime divisor of $|G|$. Combining the nilpotence, the normality and the order of groups together, we prove that if every maximal subgroup of $G$ is nilpotent or normal or has $p'$-order, then (1) $G$ is solvable; (2) $G$ has a Sylow tower; (3) There exists at most one prime divisor $q$ of $|G|$ such that $G$ is neither $q$-nilpotent nor $q$-closed, where $qneq p$.
设$G$是有限群,$p$是$|G|$的固定素数因子。结合群的幂零性、正规性和阶性,证明了如果G$的每一个极大子群幂零或正规或p $-阶,则(1)G$是可解的;(2) $G$有一个Sylow塔;(3) $|G|$最多存在一个素因子$q$,使得$G$既不是$q$-幂零又不是$q$-闭,其中$qneq p$。

We study subgroups of the group [Formula: see text] of piecewise linear orientation-preserving homeomorphisms of the unit interval [Formula: see text] that are differentiable everywhere except at finitely many real numbers, under the operation of composition. We provide a criterion for any two subgroups of [Formula: see text] which are direct products of finitely many indecomposable non-commutative groups to be non-isomorphic. As its application, we give a necessary and sufficient condition for any two subgroups of the R. Thompson group [Formula: see text] that are stabilizers of finite sets of numbers in the interval [Formula: see text] to be isomorphic, thus solving a problem by G. Golan and M. Sapir. We also show that if two stabilizers are isomorphic, then they are conjugate inside a certain group [Formula: see text].
研究了单位区间分段线性保方向同纯群[公式:见文]的子群,这些子群在除有限多个实数外处处可微。我们给出了[公式:见文]的任意两个子群是非同构的判据,这两个子群是有限多个不可分解非交换群的直接乘积。作为其应用,我们给出了R. Thompson群[公式:见文]中任意两个子群是区间[公式:见文]有限数集的稳定子群同构的充分必要条件,从而解决了G. Golan和M. Sapir的一个问题。我们还证明了如果两个稳定剂是同构的,那么它们在某一群内是共轭的[公式:见文]。
