Whitney tower concordance of classical links
This paper computes Whitney tower filtrations of classical links. Whitney towers consist of iterated stages of Whitney disks and allow a tree-valued intersection theory, showing that the associated graded quotients of the filtration are finitely generated abelian groups. Twisted Whitney towers are studied and a new quadratic refinement of the intersection theory is introduced, measuring Whitney...
متن کاملKnot Concordance, Whitney Towers and L2-signatures
We construct many examples of non-slice knots in 3-space that cannot be distinguished from slice knots by previously known invariants. Using Whitney towers in place of embedded disks, we define a geometric filtration of the 3-dimensional topological knot concordance group. As special cases of Whitney towers of height less than four, the bottom part of the filtration exhibits all classical conco...
متن کاملConcordance of links with identical Alexander invariants
Davis showed that the topological concordance class of a link in the 3-sphere is uniquely determined by its Alexander polynomial for 2-component links with Alexander polynomial one. A similar result for knots with Alexander polynomial one was shown earlier by Freedman. We prove that these two cases are the only exceptional cases, by showing that the link concordance class is not determined by t...
متن کاملA Survey of Classical Knot Concordance
In 1926 Artin [3] described the construction of knotted 2–spheres in R. The intersection of each of these knots with the standard R ⊂ R is a nontrivial knot in R. Thus a natural problem is to identify which knots can occur as such slices of knotted 2–spheres. Initially it seemed possible that every knot is such a slice knot and it wasn’t until the early 1960s that Murasugi [84] and Fox and Miln...
متن کاملConcordance Invariance of Levine-Tristram Signatures of Links
We determine for which complex numbers on the unit circle the Levine-Tristram signature and the nullity give rise to link concordance invariants. 2010 Mathematics Subject Classification: primary: 57M25, secondary: 57M27, 57N70
