  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, braid groups, quantum groups, trusses, etc...

  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 Thompson groups. The family of monoids that arise should be of independent interest. The motivation for de...
