Abstract

We prove that two cyclically linked pp-algebras of prime degree become inseparably linked under a prime to pp extension if and only if the essential pp-dimension of the pair is 2. We conclude that the essential pp-dimension of pairs of cyclically linked pp-algebras is 3 by constructing an example of a pair that does not become inseparably linked under any prime to pp extension.
