Query: A topological characterization of the Moufang property for compact
  polygons   We prove a purely topological characterization of the Moufang property for
disconnected compact polygons in terms of convergence groups. As a consequence,
we recover the fact that a locally finite thick affine building of rank 3 is a
Bruhat-Tits building if and only if its automorphism group is strongly
transitive. We also study automorphism groups of general compact polygons
without any homogeneity assumption. A compactness criterion for sets of
automorphisms is established, generalizing the theorem by Burns and Spatzier
that the full automorphism group, endowed with the compact-open topology, is a
locally compact group.
