Algebraic concordance of links
David Cimasoni, Anthony Conway, Gaetan Simian
Algebraic concordance of knots can be understood from the perspective of Seifert matrices, Blanchfield forms, and homology surgery. We initiate a systematic study of algebraic conc…

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…
