Sep24 awarded Autobiographer Sep8 comment The family of finite unions of half-open intervals forms a ring of sets It the nth term and the mth term do not intersect then you have written the empty set in a complicated way. You can delete all these different versions of writing the empty set. Sep8 comment Why is the set of functions from the naturals to the rationals a subset of $\mathcal P(\mathbb N \times \mathbb Q)$? What is your definition of a function? What is your definition of an element of $\mathcal{P}(\mathbb{N} \times \mathbb{Q})$?
