What Juris Hartmanis taught me about Reductions

Computational Complexity 2024-01-23 v1

Abstract

I was a student of Juris Hartmanis at Cornell in the late 1970's. He believed that there was great potential in studying restricted reductions. I describe here some of his influences on me and, in particular, how his insights concerning reductions helped me to prove that nondeterministic space is closed under complementation.
