# Permutations of the integers and Aut($\mathcal D_T$)

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”, appeared in Bulletin of Symbolic Logic (2018), and was presented at Workshop on Computability Theory in Waterloo, Ontario, and Workshop on Computability Theory and Foundations of Mathematics (CTFM) in Tokyo.
