Title:The structure of non-atomic randomness
Seminar:Logic Seminar
Speaker:Jan Reimann, Pennsylvania State University
We study the set NCR of infinite binary sequences that are never random with respect to a continuous Borel probability measure. We show that such sequences occur all the way through the hyperarithmetical hierarchy, and construct examples that are non-ranked, i.e. not a member of a countable effectively closed set.
