Automorphism(s) of the Turing degrees

Two papers on restrictions on automorphisms of Turing and truth-table degrees appeared in the Downey Festschrift for the Computability and Complexity Symposium 2017 in honour of Rod Downey’s 60th birthday.

One, “Permutations of the integers induce only the trivial automorphism of the Turing degrees”, is to appear in Bulletin of Symbolic Logic (2018), and will be presented at Workshop on Computability Theory in Waterloo, Ontario.
