Abstract

The content delves into computational depth relationships, focusing on Bennett's logical depth concept. It discusses strong and weak depth notions, introducing deep Π0 1 classes. The study shows that every member of a deep Π0 1 class is order-deep, providing new examples of strongly deep sequences. Additionally, it reveals that the collection of strongly deep sequences is negligible. Various results and implications are explored through detailed proofs and analyses.

Stats

For the first main result of the study, we show that every member of a Π0 1 class is order-deep.
We further show that not every strongly deep sequence is a member of a deep Π0 1 class.
Finally, we show that variants of strong depth are equivalent to weak depth.

Quotes

"No computable sequence and no Martin-Löf random sequence is strongly deep."
"Every sequence that is truth-table reducible to a random sequence with respect to a computable measure is itself random."
"The slow growth law will continue to be a useful tool in the study of notions of depth."
