Cupping with random sets

Author:

Day Adam,Miller Joseph

Abstract

We prove that a set is K K -trivial if and only if it is not weakly ML-cuppable. Further, we show that a set below zero jump is K K -trivial if and only if it is not ML-cuppable. These results settle a question of Kučera, who introduced both cuppability notions.
