His number-theoretic psi function involves taking the product over all distinct prime factors p of n of (1 + 1/p), then multiplying by n. A type of integral domain named for him is an integrally closed Noetherian domain for which every nonzero prime ideal is also a maximal ideal.
A problem named for this man is equivalent to finding the number of free distributive lattices with n generators, but it is more commonly stated as determining the number of monotonic increasing Boolean functions of n variables.

A type of integral domain named for him is an integrally closed Noetherian domain for which every nonzero prime ideal is also a maximal ideal. Another concept associated with this mathematician is a partition of the rationals into two nonempty subsets S1 and S2 such that all members of S1 are less than those of S2, and S1 has no greatest element. For 10 points, identify this mathematician who thus constructed the reals from the rationals with his namesake "cuts."
