Multivariate Alexander quandles, IV. The medial quandle of a link
Lorenzo Traldi
Joyce observed that the Alexander invariant and the medial quandle of a classical knot are equivalent to each other, as invariants. In the present paper, we discuss the rather comp…
A Characterization of Circle Graphs in Terms of Total Unimodularity
Robert Brijder, Lorenzo Traldi
A graph has an associated multimatroid , which is equivalent to the isotropic system of studied by Bouchet. In previous work it was shown that is a ci…
Multivariate Alexander quandles, III. Sublinks
Lorenzo Traldi
If is a classical link then the multivariate Alexander quandle, , is a substructure of the multivariate Alexander module, . In the first paper of this series we…
Multivariate Alexander quandles, II. The involutory medial quandle of a link (corrected)
Lorenzo Traldi
Joyce showed that for a classical knot , the involutory medial quandle is isomorphic to the core quandle of the homology group , where is the cyc…
