Abstract
We describe the prime ideals and, in particular, the maximal ideals in products R = Dλ of families (Dλ)λ of commutative rings. We show that every maximal ideal is induced by an ultrafilter on the Boolean algebra (max(Dλ)), where max(Dλ) is the spectrum of maximal ideals of Dλ, and denotes the power set. If every Dλ is in a certain class of rings including finite character domains and one-dimensional domains, we completely characterize the maximal ideals of R. If every Dλ is a Prüfer domain, we completely characterize all prime ideals of R.
