For a ring extension
is called a universally catenarian pair if every domain
, is universally catenarian. When
R is a field it is shown that the only universally catenarian pairs are those satisfying
. For
several satisfactory results are given. The second purpose of this paper is to study going-down pairs (Definition 5.1). We
characterize these pairs of rings and we establish a relationship between universally catenarian, going-down and residually
algebraic pairs.
