Algebraic concordance of links
David Cimasoni, Anthony Conway, Gaetan Simian
The paper develops algebraic tools to study when multi‑component links are concordant, introducing two new invariants derived from homology surgery and Blanchfield linking forms.

Algebraic concordance groups for links
Gaëtan Simian
We use families of generalized Seifert matrices to define algebraic concordance groups for links with non trivial Alexander polynomial. We then use these groups to recover the inva…

On Arf invariants of colored links
David Cimasoni, Gaetan Simian
Several classical knot invariants, such as the Alexander polynomial, the Levine-Tristram signature and the Blanchfield pairing, admit natural extensions from knots to links, and mo…
