Latin quandles of size

Marco Bonatto, Filippo Spaggiari

In this paper we obtain the classification of latin quandles of size where is an odd prime. In particular we have that such quandles are always subdirectly reducible but…

On Core Quandles

Filippo Spaggiari, Marco Bonatto

We characterize several properties of core quandles in terms of the properties of their underlying groups. Specifically, we characterize connected cores providing an answer to an o…

Involutive (simple) latin solutions of the Yang-Baxter equation and related (left) quasigroups

Marco Bonatto, Marco Castelli

In this paper, we study involutive non-degenerate set-theoretic solutions of the Yang-Baxter equation with regular displacement group. In particular, we completely describe the blo…

A conjecture on superconnected quandles

Marco Bonatto

We study simple superfaithful and superconnected quandles and we found counterexamples to a conjecture suggested by computational data. We provide also examples of superconnected q…

Oriented singquandles and related algebraic structures

Marco Bonatto

In this paper we consider the algebraic structures related to invariants of topological structures introduced respectively in [CEKL22] and [ADEM19]. Our main results is to show how…

Two Galois connections for left quasigroups

Marco Bonatto

We investigate two Galois connection between the congruence lattice and the lattice of subgroups of the displacement group of left quasigroups. Such connections were already studie…
