Compactness of the automorphism group of a topological parallelism on real projective 3-space: The disconnected case
arXiv:1710.05558
Abstract
We prove that the automorphism group of a topological parallelism on real projective 3-space is compact. In a preceding article it was proved that at least the connected component of the identity is compact. The present proof does not depend on that earlier result.
