Abstract.
For a ring extension \(R\subseteq S, (R, S)\) is called a universally catenarian pair if every domain \(T, R\subseteq T\subseteq S\), is universally catenarian. When R is a field it is shown that the only universally catenarian pairs are those satisfying \(tr.deg[S:R]\leq 1\). For \(dimR\geq 1\) 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.
