Ackermann function Peter Mayr Computability Theory, February 15, 2021. Question Primitive recursive functions are computable. What about the converse? We’ll see that some functions grow too fast to be primitive recursive.

Ackermann set theory. In mathematics and logic, Ackermann set theory (AST) is an axiomatic set theory proposed by Wilhelm Ackermann in 1956.
