Using a Set to Construct a Group Topology
Ellen Clay ...et al KYUNGPOOK UNIVERSITY 1997 Kyungpook mathematical journal Vol.37 No.1
The usual topology on the real line can be constructed in a natural fashion from the set (-∞, 1). It along with its opposite set (-1, ∞) and translates of these sets forms a subbasis for the usual topology. Hence the coarsets group topology on the reals containing the set (-1, ∞) is the usual topology. Many group topologies can be generated in this fashion. This paper will consider which group topologies can be generated in this fashion and which sets may be used to generate the topology.
