The study of convergence
of sequences of elements of the dual space Ĝ, for a nilpotent Lie group
G, is done by reducing the study to convergence of sequences of subgroup
representation pairs, whose subgroup component has dimension less than the
dimension of G. The main results are then applied to give a new proof to the
fact that the Kirillov correspondence is a homeomorphism for nilpotent Lie
groups.
