We examine properties of the right ideal structure of right distributive do
mains. Right distributive domains R are exactly those rings whose localizat
ions at maximal right ideals M are right chain domains R-M. On the one hand
, the paper focuses on the question in which way properties of R are carrie
d over to R-M and vice versa. We examine the problem under which conditions
two-sided ideals of R are again two-sided in the extension R-M (Lemma 2.2)
. Further, we observe the relationship between completely prime resp. semip
rime ideals of R and the extended ideals in R-M. On the other hand, we prov
e in particular that for any maximal right ideal M = R\S-M the right-S-M-sa
turation I-[M] of a completely semiprime ideal I subset of or equal to M of
R is completely prime (Theorem 2.9). A central role is played by waists of
right distributive rings which are right ideals comparable to each other i
deal, in particular there exists a largest waist W which is completely prim
e. We present a representation theorem in terms of ideals in R,. We apply t
hese results to the Jacobson radical J(R) of a right distributive domain R.
Illustrative examples are given.
