GVZ-groups, Flat groups, and CM-Groups [PDF]

open access: yesComptes 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]

open access: yesThe 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 ...

On a bottom layer in a group

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
We consider the problem of recognizing a group by its bottom layer. This problem is solved in the class of layer-finite groups. A group is layer-finite if it has a finite number of elements of every order. This concept was first introduced by S.

Solving optimization problems in emergency evacuation

open access: yesTạp chí Khoa học và Công nghệ, 2023
In this paper, we propose a method to solve the optimization problem in an emergency evacuation. Specifically, when passengers are waiting for their flight in the lounge and a fire breaks out.

SHELXT – Integrated space-group and crystal-structure determination

open access: yesActa Crystallographica Section A: Foundations and Advances, 2015
SHELXT automates routine small-molecule structure determination starting from single-crystal reflection data, the Laue group and a reasonable guess as to which elements might be present.

The density-matrix renormalization group in the age of matrix product states [PDF]

open access: yes, 2010
The density-matrix renormalization group method (DMRG) has established itself over the last decade as the leading method for the simulation of the statics and dynamics of one-dimensional strongly correlated quantum lattice systems.
