Chern-Simons invariants, SO(3) instantons, and Z/2-homology cobordism
arXiv:1009.5365
Abstract
We review the SO(3) instanton gauge theory of Fintushel and Stern and recast it in the context of 4-manifolds with cylindrical ends. Appli- cations to the Z/2-homology cobordism group of Z/2-homology 3-spheres are given.
