In this note we study whether specific elements in the second homology of specific simply connected closed $4$-manifolds can be represented by smooth or topologically flat embedded spheres. 
Embedding surfaces in 4-manifolds
We prove a surface embedding theorem for 4-manifolds with good fundamental group in the presence of dual spheres, with no restriction on the normal bundles. The new obstruction is a Kervaire–Milnor


Minimal genus in circle bundles over 3‐manifolds
An estimate is proved for the genus function in circle bundles over irreducible 3‐manifolds. This estimate is an equality in many cases, and it relates the minimal genus of the surfaces representing
Higher order intersection numbers of 2-spheres in 4-manifolds
This is the beginning of an obstruction theory for deciding whether a map f : S 2 ! X 4 is homotopic to a topologically flat embedding, in the presence of fundamental group and in the absence of dual
Foundational Essays on Topological Manifolds, Smoothings, and Triangulations.
Since Poincare's time, topologists have been most concerned with three species of manifold. The most primitive of these--the TOP manifolds--remained rather mysterious until 1968, when Kirby
The topology of four-dimensional manifolds
0. Introduction Manifold topology enjoyed a golden age in the late 1950's and 1960's. Of the mysteries still remaining after that period of great success the most compelling seemed to lie in
Topology of 4-manifolds
One of the great achievements of contemporary mathematics is the new understanding of four dimensions. Michael Freedman and Frank Quinn have been the principals in the geometric and topological
An application of gauge theory to four-dimensional topology
Soit X une u-variete compacte reguliere simplement connexe orientee avec la propriete que la forme associee Q est definie positive. Alors cette forme est equivalente, sur les entiers, a la forme
T. Lawson conjectured in [11] that the minimal genus of (m,n) 2 H2(CP 2 #CP 2 ) is given by ( |m| 1 2 ) + ( |n| 1 2 ) -this is the genus realized by the connected sum of algebraic curves in each
