GVZ-groups, Flat groups, and CM-Groups [PDF]
Comptes Rendus. Mathématique, 2021 We show that a group is a GVZ-group if and only if it is a flat group. We show that the nilpotence class of a GVZ-group is bounded by the number of distinct degrees of irreducible characters. We also show that certain CM-groups can be characterized as GVZ-groups whose irreducible character values lie in the prime field.

Group Connectivity and Group Coloring: Small Groups versus Large Groups [PDF]
The Electronic Journal of Combinatorics, 2020 A well-known result of Tutte says that if $\Gamma$ is an Abelian group and $G$ is a graph having a nowhere-zero $\Gamma$-flow, then $G$ has a nowhere-zero $\Gamma'$-flow for each Abelian group $\Gamma'$ whose order is at least the order of $\Gamma$. Jaeger, Linial, Payan, and Tarsi observed that this does not extend to their more general concept of ...

Learning in a Group, as a Group, and between Groups [PDF]
CBE—Life Sciences Education, 2019 Learning in groups is a common feature of science classrooms. The three articles I have chosen to feature in this installment of Current Insights reflect recent research of group learning at different scales. The first examines within-group dynamics, identifying interactions among students that allow scientific sense-making discussions to begin and ...

On the classification of easy quantum groups [PDF]
, 2013 In 2009, Banica and Speicher began to study the compact quantum subgroups of the free orthogonal quantum group containing the symmetric group S_n. They focused on those whose intertwiner spaces are induced by some partitions. These so-called easy quantum

Covering Groups of Nonconnected Topological Groups and 2-Groups [PDF]
, 2019 We investigate the universal cover of a topological group that is not necessarily connected. Its existence as a topological group is governed by a Taylor cocycle, an obstruction in 3-cohomology.

From mapping class groups to automorphism groups of free groups [PDF]
, 2005 We show that the natural map from the mapping class groups of surfaces to the automorphism groups of free groups, induces an infinite loop map on the classifying spaces of the stable groups after plus construction.

Frobenius-like groups as groups of automorphisms [PDF]
, 2014 A finite group FH is said to be Frobenius-like if it has a nontrivial nilpotent normal subgroup F with a nontrivial complement H such that FH/[F,F] is a Frobenius group with Frobenius kernel F/[F,F].

People and Nature, 2023 Adder ( Vipera berus ) populations are experiencing declines in many countries, including the United Kingdom. Perceptions of adders and other venomous snakes are generally negative, making conservation of these species a challenge, and persecution ...

SOME FUNDAMENTAL PROPERTIES OF HEAPS
Barekeng, 2023 Heap is defined to be a non-empty set with ternary operation satisfying associativity, that is for every and satisfying Mal’cev identity, that is for all . There is a connection between heaps and groups.

To group or not to group? Group sizes for requirements elicitation
Information and Software Technology, 2023 Context: Requirement elicitation can be done by individuals or by groups. Computer-based system development life-cycle models suggest having people working together for many steps. Also, recommendations about analysis and design methods indicate that some processes could take advantage of group work.
