Abelian invariants of doubly slice links

We provide obstructions to a link in S3 arising as the cross section of any number of unlinked spheres in S4. Our obstructions arise from the multivariable signature, the Blanchfield form and generalised Seifert matrices. We also obtain obstructions in the case of surfaces of higher genera, leading to a lower bound on the doubly slice genus of links.

Stabilization and satellite construction of doubly slice links
A 2-component oriented link in S3 is called weakly doubly slice if it is a cross-section of an unknotted sphere in S4, and strongly doubly slice if it is a cross-section of a 2-component trivial…

Milnor invariants and twisted Whitney towers
This paper describes the relationship between the first non‐vanishing Milnor invariants of a classical link and the intersection invariant of a twisted Whitney tower. This is a certain 2‐complex in…
SEIFERT MATRICES AND BOUNDARY LINK COBORDISMS
To an m-component boundary link of odd dimension, a matrix is associated by taking the Seifert pairing on a Seifert surface of the link. An algebraic description of the set of boundary link cobordism…
TWISTED ACYCLICITY OF A CIRCLE AND SIGNATURES OF A LINK
Homology of the circle with non-trivial local coefficients is trivial. From this well-known fact we deduce geometric corollaries involving codimension-two links. In particular, the Murasugi–Tristram…
Band Number and the Double Slice Genus
We study the double slice genus of a knot, a natural generalization of slice genus. We define a notion called band number, a natural generalization of band unknotting number, and prove it is an upper…
Doubly slice Montesinos links
This paper compares notions of double sliceness for links. The main result is to show that a large family of 2-component Montesinos links are not strongly doubly slice despite being weakly doubly…
Blanchfield forms and Gordian distance
Given a link in S3S3 we will use invariants derived from the Alexander module and the Blanchfield pairing to obtain lower bounds on the Gordian distance between links, the unlinking number and…
Embedding Seifert manifolds in S^4
Using an obstruction based on Donaldson’s theorem on the intersection forms of definite 4-manifolds, we determine which connected sums of lens spaces smoothly embed in S4. We also find constraints…
The signature of a splice
TLDR
The behavior of the signature of colored links under the splice operation is studied and it is shown that the signature is almost additive, with a correction term independent of the links.
The Blanchfield pairing of colored links
It is well known that the Blanchfield pairing of a knot can be expressed using Seifert matrices. In this paper, we compute the Blanchfield pairing of a colored link with non-zero Alexander…
Polynomial splittings of correction terms and doubly slice knots
We show that if the connected sum of two knots with coprime Alexander polynomials is doubly slice, then the Ozsvath–Szabo correction terms, as smooth double sliceness obstructions, vanish for both…
