    Sharp thresholds for a phase transition related to weakly increasing sequences (English)
    0 references
    In the paper the recursion-theoretic complexity of certain assertions related to the Erdős-Szekeres theorem are investigated. It is shown that resulting density principles give rise to Ackermannian growth. These assertions are then parametrized with respect to a number-theoretic function \(f\). It is investigated for which functions \(f\) Ackermannian growth is still preserved.
