Today, April 14, my former teacher, and for many years, colleague and friend, Jens Erik Fenstad, passed away after a long struggle with a Covid-19 infection.
Jens Erik was active in the process of axiomatising general computability. He organised the two successful conferences "Generalized Recursion Theory" in 1972 and " Generalized Recursion Theory II" in 1977. He is also the author of the volume "General Recursion Theory An Axiomatic Approach" in the Omega series from 1980.
