An adjunction criterion in almost-complex 4-manifolds

The adjunction inequality is a key tool for bounding the genus of smoothly embedded surfaces in 4-manifolds. Using gauge-theoretic invariants, many versions of this inequality have been established

Contact 5-manifolds and smooth structures on Stein 4-manifolds

We show that, under a certain condition, contact 5-manifolds can `coarsely' distinguish smooth structures on compact Stein 4-manifolds via contact open books. We also give a simple sufficient

Topology of symplectic fillings of contact 3-manifolds

These are some lecture notes for my mini-course in the Gradu ate Workshop on 4-Manifolds, August 18-22, 2014 at the Simons Center for G eometry and Physics. Most of this manuscript is an adaptation

Correction to: Stein and Weinstein structures on disk cotangent bundles of surfaces

In 1998, Gompf described a Stein domain structure on the disk cotangent bundle of any closed surface S, by a Legendrian handlebody diagram. We prove that the boundary of this Stein domain is

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 \ ˚ B 4 , with boundary a knot K ⊂ S 3 . We give several methods to bound the genus

Exotic Mazur manifolds and knot trace invariants

Symplectic 4–manifolds, Stein domains, Seiberg–Witten theory and mapping class groups

It is less transparent how mapping class groups are related to 4–dimensional topology. By results of Donaldson and Gompf, closed symplectic manifolds (admitting Lefschetz fibration or Lefschetz

Exotic ribbon disks and symplectic surfaces.

We construct pairs of surfaces in symplectic 4-manifolds that are topologically isotopic yet are not equivalent under any ambient diffeomorphism, including the first such examples of holomorphic

Geodesible contact structures on $3$–manifolds

In this paper, we study and almost completely classify contact structures on closed 3‐ manifolds which are totally geodesic for some Riemannian metric. Due to previously known results, this amounts

A NOTE ON CONTACT STRUCTURES

We construct two contact structures on a homology sphere M , that are homotopic through 2-plane fields, but are not isotopic as contact structures. A diffeomorphism of M permutes these two contact

Tight contact structures and Seiberg–Witten invariants

Contact structures are the odd-dimensional analogue of symplectic structures. Although much is known, the present understanding of both kinds of structures is far from complete, even in low

Handlebody construction of Stein surfaces

The topology of Stein surfaces and contact 3-manifolds is studied by means of handle decompositions. A simple characterization of homeomorphism types of Stein surfaces is obtained-they correspond to

A product formula for the seiberg-witten invariants and the generalized thom conjecture

The Thorn Conjecture asserts that any compact, embedded surface in CP of degree d > 0 must have genus at least as large as the smooth algebraic curve of the same degree, namely (d — l)(d — 2)/2. More

IMMERSED SPHERES IN 4-MANIFOLDS AND THE IMMERSED THOM CONJECTURE

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 regarding

A fake compact contractible 4-manifold

Here we construct a fake smooth structure on a compact contractible 4-manifold W , where W is a well-known Mazur manifold obtained by attaching in two-handle to S x B along its boundary as in Figure

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 the
