Abstract :
It is shown that if two submeasures on N that are lim sup’s of sequences of measures have
the same zero sets, and one is nonatomic, so is the other, and they are (ε-δ)-equivalent.
Moreover, if a submeasure η is the lim sup of a sequence of lower semi-continuous (lsc)
submeasures and is 0-dominated by the so-called core γ • of an lsc submeasure γ , then
η is also (ε-δ)-dominated by γ •. And if a submeasure η of this type is 0-dominated by
a nonatomic submeasure, then it is nonatomic as well
