On the area of the complement of the invariant component of certain b-groups and on sequences of terminal regular b-groups

Abstract

In this paper, we give a lower estimate of the Euclidian area of non-invariant components of b-group with suitable normalizations which contains triangle groups as component subgroups. As an application of the estimate, we obtain a sufficient condition for a sequence of terminal regular b-group to converge to a totally degenerate group.
