Continuity set
In measure theory, a continuity set of a measure ''μ'' is any Borel set ''B'' such that
:
\mu(\partial B) = 0\,.

where \partial B is the boundary set of ''B''. For signed measures, one asks that
:
|\mu|(\partial B) = 0\,.

The class of all continuity sets for given measure ''μ'' forms a ring.〔Cuppens, R. (1975) Decomposition of multivariate probability. Academic Press, New York.〕
Similarly, for a random variable ''X'' a set ''B'' is called continuity set if
:
\Pr(\in \partial B ) = 0,

otherwise ''B'' is called the ''discontinuity set''. The collection of all discontinuity sets is sparse. In particular, given any collection of sets with pairwise disjoint boundaries, all but at most countably many of them will be the continuity sets.〔van der Vaart (1998) Asymptotic statistics. Cambridge University Press. ISBN 978-0-521-78450-4. Page 7〕
The continuity set ''C''(''f'') of a function ''f'' is the set of points where ''f'' is continuous.
