Reidemeister torsion, the Thurston norm and Harvey's invariants
Stefan Friedl
Recently twisted and higher order Alexander polynomials were used by Cochran, Harvey, Friedl--Kim and Turaev to give lower bounds on the Thurston norm. We first show how Reidemeist…
Twisted Alexander norms give lower bounds on the Thurston norm
Stefan Friedl, Taehee Kim
We introduce twisted Alexander norms of a compact connected orientable 3-manifold with first Betti number bigger than one generalizing norms of McMullen and Turaev. We show that tw…
Thurston norm, fibered manifolds and twisted Alexander polynomials
Stefan Friedl, Taehee Kim
Every element in the first cohomology group of a 3--manifold is dual to embedded surfaces. The Thurston norm measures the minimal `complexity' of such surfaces. For instance the Th…
Link concordance, boundary link concordance and eta invariants
Stefan Friedl
We study the eta-invariants of links and show that in many cases they form link concordance invariants, in particular that many eta-invariants vanish for slice links. This result c…
Algorithm for finding boundary link Seifert matrices
Stefan Friedl
We explain an algorithm for finding a boundary link Seifert matrix for a given Alexander polynomial. The algorithm depends on several choices and therefore makes it possible to fin…
