Idempotents, automorphism groups, and commutator widths of quandle algebras

Birama Sangare, Luc Ta

The paper develops the theory of quandle algebras. We show that over integral domains of characteristic other than 2, quandle algebras of ordered commutative quandles have no nontr…

On medial Latin quandles and affine modules

Luc Ta

The paper shows that the categories of Latin and commutative medial quandles are equivalent to categories of affine modules over a Laurent polynomial ring and over the dyadic ratio…

Graph quandles: Generalized Cayley graphs of racks and right quasigroups

Luc Ta

This article lays the foundations for an analogue of geometric group theory that studies actions on graphs by right quasigroups, including racks and quandles. We study markings of…

Distinguishing Power of 4-Legendrian Permutation Racks

Luc Ta, Peyton Phinehas Wood

We study 4-Legendrian racks and their effectiveness at distinguishing Legendrian knots. We prove that permutation racks with 4-Legendrian rack structures cannot distinguish Legendr…

From affine algebraic racks to Leibniz algebras and Yang-Baxter operators

Luc Ta

We introduce analogues of algebraic groups called algebraic racks, which are pointed rack objects in the category of schemes over a ground field. Addressing a problem of Loday, we…

Groups versus quandle-like invariants of 3-manifolds

Luc Ta

Risandles are nonassociative algebraic structures recently introduced to construct invariants of 3-manifolds. In this note, we show that the categories of groups and nonempty, fait…
