Continuity set

In measure theory, a branch of mathematics, a continuity set of a measure μ is any Borel set B such that

where is the boundary set of B. For signed measures, one asks that

The class of all continuity sets for given measure μ forms a ring.[1]

Similarly, for a random variable X a set B is called continuity set if

Continuity set of a function

The continuity set C(f) of a function f is the set of points where f is continuous.

gollark: There are many things people should know. But some of them school is effectively unable to teach, and others really should be easy to learn independently for competent sane people.
gollark: These are difficult skills. Do you think they will be taught well by an adult not selected much for it in an environment which generally pushes conformity?
gollark: No, this is an awful idea.
