    Notes: Abstract. Given an improper action (= cell stabilizers are infinite) of a group G on a CW-complex $ {\cal X} $ , we present criteria, based on connectivity at infinity properties of the cell stabilizers under the action of G that imply connectivity at infinity properties for G. A refinement of this idea yields information on the topology at infinity of Artin groups, and it gives significant progress on the question of which Artin groups are duality groups.
