A characterization of central extensions in the variety of quandles / V. Even, M. Gran, A. Montoli. - In: THEORY AND APPLICATIONS OF CATEGORIES. - ISSN 1201-561X. - 31(2016), pp. 201-216.
Abstract:
The category of symmetric quandles is a Mal’tsev variety whose subvariety of abelian symmetric quandles is the category of abelian algebras. We give an algebraic description of the quandle extensions that are central for the adjunction between the variety of quandles and its subvariety of abelian symmetric quandles.
