A classification of hull operators in archimedean lattice-ordered groups with unit [PDF]
The category, or class of algebras, in the title is denoted by $\bf W$. A hull operator (ho) in $\bf W$ is a reflection in the category consisting of $\bf W$ objects with only essential embeddings as morphisms.

Presentations for Quaternionic S-Unit Groups [PDF]
We give an algorithm for presenting S-unit groups of an order in a definite rational quaternion algebra B such that for every p ∈ S at which B splits, the localization of at p is maximal, and all left ideals of of norm p are principal. We then apply this

Both humans and pet dogs are more prone to develop allergies in urban than in rural environments, which has been associated with the differing microbial exposures between areas.

BackgroundDuring the COVID-19 pandemic, a variable percentage of patients with SARS-CoV-2 infection failed to elicit humoral response. This study investigates whether patients with undetectable SARS-CoV-2 IgG are able to generate SARS-CoV-2 memory T ...

Unit groups of integral group rings [PDF]
Let U ( Z G ) U(\mathbb {Z}G) be the unit group of the integral group ring Z G \mathbb {Z}G . A group G G satisfies ( ∗ ) ({\ast }) if either the set

On sets with unit Hausdorff density in homogeneous groups
It is a longstanding conjecture that given a subset E of a metric space, if E has unit $\mathscr {H}^{\alpha }\llcorner E$ -density almost everywhere, then E is an $\alpha $ -rectifiable set. We prove this conjecture under the assumption that

On unit group of finite semisimple group algebras of non-metabelian groups up to order 72 [PDF]
We characterize the unit group of semisimple group algebras $\mathbb{F}_qG$ of some non-metabelian groups, where $F_q$ is a field with $q=p^k$ elements for $p$ prime and a positive integer $k$.

Unit Groups of group algebras of certain quasidihedral group
Let $F_{q}$ be any finite field of characteristic $p>0$ having $q = p^{n}$ elements. In this paper, we have obtained the complete structure of unit groups of group algebras $F_{q}[QD_{2^k}]$, for $k = 4$ and $5$, for any prime $p>0$, where $QD_{2^k}$ is quasidihedral group of order $2^k$

Free Unit Groups in Group Algebras
Let \(K\) be a field and \(G\) be a finite group, which satisfies one of the following conditions: (i) \(K\) is of characteristic \(0\) and \(G\) is nonabelian; (ii) \(K\) is of characteristic \(p\) and for the largest normal \(p\)-subgroup \(P\) of \(G\) the factor-group \(G/P\) is nonabelian.

Which alternating and symmetric groups are unit groups [PDF]
We prove there is no ring with unit group isomorphic to S_n for n \geq 5 and that there is no ring with unit group isomorphic to A_n for n \geq 5, n \neq 8.
