The intersection of each of these knots with the standard R3 ⊂ R4 is a nontrivial knot in R3. 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 [86] and Fox and Milnor [24, 25] succeeded at proving that some knots are not slice. Slice knots can be used to define an equivalence relation on the set of knots in S3: knots K and J are equivalent if K# − J is slice. With this equivalence the set of knots becomes a group, the concordance group of knots. Much progress has been made in studying slice knots and the concordance group, yet some of the most easily asked questions remain untouched. -

STABLY SLICE DISKS OF LINKS ANTHONY CONWAY AND MATTHIAS NAGEL Abstract. We define the stabilizing number sn(K) of a knot K ⊂ S3 as the minimal number n of S2 × S2 connected summands required for K to bound a nullhomologous locally flat disk in D4# nS2 × S2. This quantity is defined when the Arf invariant of K is zero. We show that sn(K) is bounded below by signatures and Casson-Gordon invariants and bounded above by top the topological 4-genus g4 (K). We provide an infinite family of examples top with sn(K) < g4 (K). 1. Introduction Several questions in 4{dimensional topology simplify considerably after con- nected summing with sufficiently many copies of S2 S2. For instance, Wall showed that homotopy equivalent, simply-connected smooth× 4{manifolds become diffeo- morphic after enough such stabilizations [Wal64]. While other striking illustrations of this phenomenon can be found in [FK78, Qui83, Boh02, AKMR15, JZ18], this paper focuses on embeddings of disks in stabilized 4{manifolds. A link L S3 is stably slice if there exists n 0 such that the components of L bound a⊂ collection of disjoint locally flat nullhomologous≥ disks in the mani- fold D4# nS2 S2: The stabilizing number of a stably slice link is defined as × sn(L) := min n L is slice in D4# nS2 S2 : f j × g Stably slice links have been characterized by Schneiderman [Sch10, Theorem 1, Corollary 2]. We recall this characterization in Theorem 2.9, but note that a knot K is stably slice if and only if Arf(K) = 0 [COT03]. -

The Arf and Sato Link Concordance Invariants
transactions of the american mathematical society Volume 322, Number 2, December 1990 THE ARF AND SATO LINK CONCORDANCE INVARIANTS RACHEL STURM BEISS Abstract. The Kervaire-Arf invariant is a Z/2 valued concordance invari- ant of knots and proper links. The ß invariant (or Sato's invariant) is a Z valued concordance invariant of two component links of linking number zero discovered by J. Levine and studied by Sato, Cochran, and Daniel Ruberman. Cochran has found a sequence of invariants {/?,} associated with a two com- ponent link of linking number zero where each ßi is a Z valued concordance invariant and ß0 = ß . In this paper we demonstrate a formula for the Arf invariant of a two component link L = X U Y of linking number zero in terms of the ß invariant of the link: arf(X U Y) = arf(X) + arf(Y) + ß(X U Y) (mod 2). This leads to the result that the Arf invariant of a link of linking number zero is independent of the orientation of the link's components. We then estab- lish a formula for \ß\ in terms of the link's Alexander polynomial A(x, y) = (x- \)(y-\)f(x,y): \ß(L)\ = \f(\, 1)|. Finally we find a relationship between the ß{ invariants and linking numbers of lifts of X and y in a Z/2 cover of the compliment of X u Y . 1. Introduction The Kervaire-Arf invariant [KM, R] is a Z/2 valued concordance invariant of knots and proper links. The ß invariant (or Sato's invariant) is a Z valued concordance invariant of two component links of linking number zero discov- ered by Levine (unpublished) and studied by Sato [S], Cochran [C], and Daniel Ruberman. -

UNKNOTTING NUMBER of a KNOT 1. Introduction an H(2)
H(2)-UNKNOTTING NUMBER OF A KNOT TAIZO KANENOBU AND YASUYUKI MIYAZAWA Abstract. An H(2)-move is a local move of a knot which is performed by adding a half-twisted band. It is known an H(2)-move is an unknot- ting operation. We define the H(2)-unknottiing number of a knot K to be the minimum number of H(2)-moves needed to transform K into a trivial knot. We give several methods to estimate the H(2)-unknottiing number of a knot. Then we give tables of H(2)-unknottiing numbers of knots with up to 9 crossings. 1. Introduction An H(2)-move is a change in a knot projection as shown in Fig. 1(a); note that both diagrams are taken to represent single component knots, and so the strings are connected as shown in dotted arcs. Since we obtain the diagram by adding a twisted band to each of these knots as shown in Fig. 1(b), it can be said that each of the knots is obtained from the other by adding a twisted band. It is easy to see that an H(2)-move is an unknotting operation; see [9, Theorem 1]. We call the minimum number of H(2)-moves needed to transform a knot K into another knot K0 the H(2)-Gordian distance from 0 0 K to K , denoted by d2(K, K ). In particular, the H(2)-unknottiing number of K is the H(2)-Gordian distance from K to a trivial knot, denoted by u2(K). -
Arxiv:Math/0207238V1 [Math.GT] 25 Jul 2002 an Integral Generalization
To V.I.Arnold with admiration An integral generalization of the Gusein-Zade–Natanzon theorem Sergei Chmutov One of the useful methods of the singularity theory, the method of real morsifications [AC0, GZ] (see also [AGV]) reduces the study of discrete topological invariants of a critical point of a holomorphic function in two variables to the study of some real plane curves immersed into a disk with only simple double points of self-intersection. For the closed real immersed plane curves V.I.Arnold [Ar] found three simplest first order invariants J ± and St. Arnold’s theory can be easily adapted to the curves immersed into a disk. In [GZN] S.M.Gusein-Zade and S.M.Natanzon proved that the Arf invariant of a singularity is equal to J −/2(mod 2) of the corresponding immersed curve. They used the definition of the Arf invariant in terms of the Milnor lattice and the intersection form of the singularity. However it is equal to the Arf invariant of the link of singularity, the intersection of the singular complex curve with a small sphere in C2 centered at the singular point. In knot theory it is well known (see, for example [Ka]) that Arf invariant is the mod 2 reduction of some integer-valued invariant, the second coefficient of the Conway polynomial, or the Casson invariant [PV]. Arnold’s J −/2 is also an integer-valued invariant. So one might expect a relation between these integral invariants. A few years ago N.A’Campo [AC1, AC2] invented a construction of a link from a real curve immersed into a disk. -

Noncommutative Knot Theory 1 Introduction
ISSN 1472-2739 (on-line) 1472-2747 (printed) 347 Algebraic & Geometric Topology Volume 4 (2004) 347–398 Published: 8 June 2004 ATG Noncommutative knot theory Tim D. Cochran Abstract The classical abelian invariants of a knot are the Alexander module, which is the first homology group of the the unique infinite cyclic covering space of S3 − K , considered as a module over the (commutative) Laurent polynomial ring, and the Blanchfield linking pairing defined on this module. From the perspective of the knot group, G, these invariants reflect the structure of G(1)/G(2) as a module over G/G(1) (here G(n) is the nth term of the derived series of G). Hence any phenomenon associated to G(2) is invisible to abelian invariants. This paper begins the systematic study of invariants associated to solvable covering spaces of knot exteriors, in par- ticular the study of what we call the nth higher-order Alexander module, G(n+1)/G(n+2) , considered as a Z[G/G(n+1)]–module. We show that these modules share almost all of the properties of the classical Alexander module. They are torsion modules with higher-order Alexander polynomials whose degrees give lower bounds for the knot genus. The modules have presenta- tion matrices derived either from a group presentation or from a Seifert sur- face. They admit higher-order linking forms exhibiting self-duality. There are applications to estimating knot genus and to detecting fibered, prime and alternating knots. There are also surprising applications to detecting symplectic structures on 4–manifolds. -
