Limits of the Tristram--Levine signature function
Maciej Borodzik, Jakub Zarzycki
We show that under a precise condition on the single variable Alexander polynomial, the limit at of the Tristram--Levine signature of a link is determined by the linking matrix…

Real Seifert forms, Hodge numbers and Blanchfield pairings
Maciej Borodzik, Jakub Zarzycki
In this survey article we present connections between Picard--Lefschetz invariants of isolated hypersurface singularities and Blanchfield forms for links. We emphasize the unifying…
