Abstract

In this paper we prove the following result: an inductive limit ( E , t ) = ind ( E n , t n ) is regular if and only if for each Mackey null sequence ( x k ) in ( E , t ) there exists n = n ( x k ) such that ( x k ) is contained and bounded in ( E n , t n ) . From this we obtain a number of equivalent descriptions of regularity.
