Groups of order p^4 as additive groups of local nearrings
It is not true that any finite group is the additive group of a nearring with identity. Therefore it is important to determine such groups and to classify some classes of nearrings with identity on …

Pre-Lie rings and classification of braces
Braces are algebraic objects introduced by W. Rump in 2007 to help the study of non-degenerate, involutive, set theoretic solutions to the Yang-Baxter equation. Braces have been linked to many other objects of interest - Hopf-Galois extensions, …

Higher dimensional generalizations of the Thompson groups via higher rank graphs
We show how to construct a family of groups from a family of monoids that generalize free monoids. In the case of free monoids on two or more finite generators, we get back the familiar …
