Abelian invariants of doubly slice links
نویسندگان
چکیده
We provide obstructions to a link in $S^3$ arising as the cross section of any number unlinked spheres $S^4$. Our arise from multivariable signature, Blanchfield form and generalised Seifert matrices. also obtain case surfaces higher genera, leading lower bound on doubly slice genus links.

Deligne-Beilinson cohomology and abelian links invariants
For the abelian Chern-Simons field theory, we consider the quantum functional integration over the Deligne-Beilinson cohomology classes and we derive the main properties of the observables in a generic closed orientable 3-manifold. We present an explicit pathintegral non-perturbative computation of the Chern-Simons links invariants in the case of the torsion-free 3-manifolds S, S × S and S × Σg.
متن کاملAbelian Invariants of Satellite Knots
A knot in S 3 whose complement contains an essential** torus is called a satellite knot. In this paper we discuss algebraic invariants of satellite knots, giving short proofs of some known results as well as new results. To each essential torus in the complement of an oriented satellite knot S , one may associate two oriented knots C and E (the companion and embellishment) and an integer w (the...
متن کاملSignature Invariants of Links from Irregular Covers and Non-abelian Covers
Abstract. Signature invariants of odd dimensional links from irregular covers and non-abelian covers of complements are obtained by using the technique of Casson and Gordon. We show that the invariants vanish for slice links and can be considered as invariants under Fm-link concordance. We illustrate examples of links that are not slice but behave as slice links for any invariants from abelian ...
متن کاملDoubly slice knots with low crossing number
A knot in S is doubly slice if it is the cross-section of an unknotted two-sphere in S. For low-crossing knots, the most complete work to date gives a classification of doubly slice knots through 9 crossings. We extend that work through 12 crossings, resolving all but four cases among the 2,977 prime knots in that range. The techniques involved in this analysis include considerations of the Ale...
متن کاملAnalytic Invariants of Boundary Links
Using basic topology and linear algebra, we define a plethora of invariants of boundary links whose values are power series with noncommuting variables. These turn out to be useful and elementary reformulations of an invariant originally defined by M. Farber [Fa2].
