Topology of automorphism groups of parabolic geometries
We prove for the automorphism group of an arbitrary parabolic geometry that the – and –topologies coincide, and the group admits the structure of a Lie group in this topology. We further show that this automorphism group is closed in the homeomorphism group of the underlying manifold.
