We give infinitely many knots in S3 that are not smoothly H-slice (that is, bounding a null-homologous disk) in many 4-manifolds but they are topologically H-slice. In particular, we give such knots in punctured elliptic surfaces E(2n). In addition, we give obstructions to codimension-0 embedding of weak symplectic fillings with b3 = 0 into closed symplectic 4-manifolds with b1 = 0 and b + 2 ≡ 3 mod 4. We also show that any weakly symplectically fillable 3-manifold bounds a 4-manifold with at… Expand

From zero surgeries to candidates for exotic definite four-manifolds
One strategy for distinguishing smooth structures on closed 4-manifolds is to produce a knot K in S that is slice in one smooth filling W of S but not slice in some homeomorphic smooth filling W ′.Expand
Involutions, knots, and Floer K-theory
We establish a version of Seiberg–Witten FloerK-theory for knots, as well as a version of Seiberg–Witten Floer K-theory for 3-manifolds with involutions. The main theorem is a 10/8-type inequalityExpand


Symplectic fillings and positive scalar curvature
Let X be a 4-manifold with contact boundary. We prove that the monopole invariants of X introduced by Kronheimer and Mrowka vanish under the following assumptions: (i) a connected component of theExpand
Relative genus bounds in indefinite four-manifolds
Given a closed four-manifold X with an indefinite intersection form, we consider smoothly embedded surfaces in X \ B̊, with boundary a knot K ⊂ S. We give several methods to bound the genus of suchExpand
Intersection Forms of Spin 4-Manifolds and the Pin(2)-Equivariant Mahowald Invariant.
In studying the "11/8-Conjecture" on the Geography Problem in 4-dimensional topology, Furuta proposed a question on the existence of Pin(2)-equivariant stable maps between certain representationExpand
A gluing theorem for the relative Bauer-Furuta invariants
In a previous paper we have constructed an invariant of fourdimensional manifolds with boundary in the form of an element in the stable homotopy group of the Seiberg-Witten Floer spectrum of theExpand
The introduction of the Seiberg Witten monopole equations ([SW1],[SW2],[W]) has served to make the study of smooth 4-manifolds more accessible. Many of the important earlier theorems regardingExpand
Bounds on genus and geometric intersections from cylindrical end moduli spaces
In this paper we present a way of computing a lower bound for genus of any smooth representative of a homology class of positive self-intersection in a smooth four-manifold $X$ with second positiveExpand
Configurations of surfaces in 4-manifolds
We consider collections of surfaces { F,} smoothly embedded, except for a finite number of isolated singularities, self-intersections, and mutual intersections, in a 4-manifold M. A small 3-sphereExpand
Instantons, concordance, and whitehead doubling
We use moduli spaces of instantons and Chern-Simons invariants of flat connections to prove that the Whitehead doubles of (2;2 n − 1) torus knots are independent in the smooth knot concordance group;Expand
Bounds on genus and configurations of embedded surfaces in 4-manifolds
For several embedded surfaces with zero self-intersection number in 4-manifolds, we show that an adjunction-type genus bound holds for at least one of the surfaces under certain conditions. ForExpand
The Genus of Embedded Surfaces in the Projective Plane
1. Statement of the result The genus of a smooth algebraic curve of degree d in CP is given by the formula g = (d − 1)(d − 2)/2. A conjecture sometimes attributed to Thom states that the genus of theExpand
