Two papers which changed my life: Milnor's seminal work on flat manifolds and flat bundles
arXiv:1108.0216
Abstract
We survey developments arising from Milnor's 1958 paper, "On the existence of a connection with curvature zero" and his 1977 paper, "On fundamental groups of complete affinely flat manifolds".
29 pages, 7 figures, presented at "Frontiers in Complex Dynamics" in celebration of John Milnor's 80th birthday (Banff International Research Station, 24 February 2011)
