Measurable space
Set
context | $ X $ |
definiendum | $ \langle X,\Sigma\rangle\in \mathrm{MeasurableSpace}(X) $ |
postulate | $ \Sigma \in \mathrm{SigmaAlgebra}(X) $ |
Discussion
Every σ-algebra gives us a measurable space.
Predicates
We call a set $X$ measurable if there is a sigma-algebra over it.
