# The Conley index, gauge theory, and triangulations

@article{Manolescu2013TheCI, title={The Conley index, gauge theory, and triangulations}, author={Ciprian Manolescu}, journal={Journal of Fixed Point Theory and Applications}, year={2013}, volume={13}, pages={431-457} }

This is an expository paper about Seiberg–Witten Floer stable homotopy types.We outline their construction, which is based on the Conley index and finite-dimensional approximation. We then describe several applications, including the disproof of the high-dimensional triangulation conjecture.
