A New Characterization of Totally Projective Groups of Cardinality ℵ1

A new characterization is given for totally projective groups of cardinality not exceeding ℵ1. The new description is in terms of what we call a v-basis. The question about the structure of larger groups having a v-basis is left open, but we establish some closure properties of such groups. Full description
