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 ...

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.

An experimental evaluation of grouping definitions for moving entities
Journal of Spatial Information Science, 2022 One important pattern analysis task for trajectory data is to find a group: a set of entities that travel together over a period of time. In this paper, we compare four definitions of groups by conducting extensive experiments using various data sets ...

The Fundamental Group of a Group Manifold [PDF]
Proceedings of the National Academy of Sciences, 1934 The study of the interrelations between group structures and topological structures is one of the interesting recent developments of group theory. It has become well known that a space @ which is at the same time a continuous group cannot be of arbitrary topological structure.
