When is a 2-Power Cyclotomic Extension cyclic?

Sophie Marques, Elizabeth Mrema

This paper characterizes the cyclicity property of -power cyclotomic extensions through various means: the structure of the Galois groups, the nature of their subextensions, tow…

Gluing Data categories and gluing data functors

Sophie Marques, Damas Mgani

We present a novel approach to the concept of gluing in mathematics by introducing the notions of a gluing data category and a gluing data functor. Our work provides a formal categ…

Near-field structures on a given scalar group

Sophie Marques, Leandro Boonzaaier

With this paper, we gain a better understanding of the set of near-field structures on a fixed scalar group. If we were able to describe all near-field structures on a fixed scalar…

Near-linear algebra

Sophie Marques, Daniella Moore

In this paper, we prove that the world of near-vector spaces allows us to work with non-linear problems and yet, gives access to most of the tools linear algebra has to offer. We e…

A note on quadratic cyclotomic extensions

Sophie Marques, Elizabeth Mrema

This paper provides two characterizations of the primitive roots of unity in quadratic cyclotomic extensions over arbitrary fields. Firstly, we introduce a mapping from $\mathbb{N}…

The geometry of the moduli Space of non-cyclic biquadratic field extensions

Mpendulo Cele, Sophie Marques

In this paper, we investigate the existence of an elementary abelian closure in characteristic not for biquadratic extensions. We discover that it exists for any non-cyclic ext…
