“…Such groups are parametrised by a triple (A, B, H), where H is a sequence of simple groups (basically Z with different positive cones) and A and B sequences of positive integers, all subject to certain axioms. The proof of the key embedding result, established in [15,Theorem 2.11], is based on the fact that these groups are isomorphic to a direct limit of an inductive system ((Z, G + n ), f n,n+1 ) such that, for every n in N, the map f n,n+1 :…”
