Ackermann function Categories Mathematics Theory of computation From Wikipedia, the free encyclopedia. In mathematics and computer science , the Ackermann function (also known as Ackermann-Peter function ) is an important example in the theory of computation . It is a recursive function which takes two natural numbers as arguments and returns a natural number as its value. Table of contents showTocToggle("show","hide") 1 Definition 2 Recursive, but not primitive recursive 3 Table of values 4 Intuitive explanation ... edit Definition The Ackermann function is defined recursively for non-negative integers m and n as follows: edit Recursive, but not primitive recursive The Ackermann function grows extremely fast; A . This extreme growth can be exploited to show that the computable function f n A n n ) grows faster than any primitive recursive function and is therefore not primitive recursive. edit Table of values Values of A m n m n n n n n n A A A n + 3 terms) A A A A A A A A A A A (5, A(6, 1)) A A A A It might be noted that for each item, we need to compute its predecessor in the row just to find the position (index in programming terms) at which to look up the item in the previous row.

Historical development of Hilbert's Program 1.1 Early work on foundations Hilbert's work on the foundations of mathematics has its roots in his work on geometry of the 1890s, culminating in his influential textbook Foundations of Geometry ) (see 19th Century Geometry ). Hilbert believed that the proper way to develop any scientific subject rigorously required an axiomatic approach. In providing an axiomatic treatment, the theory would be developed independently of any need for intuition, and it would facilitate an analysis of the logical relationships between the basic concepts and the axioms. Of basic importance for an axiomatic treatment are, so Hilbert, investigation of the independence and, above all, of the consistency of the axioms. For the axioms of geometry, consistency can be proved by providing an interpretation of the system in the real plane, and thus, the consistency of geometry is reduced to the consistency of analysis. The foundation of analysis, of course, itself requires an axiomatization and a consistency proof. Hilbert provided such an axiomatization in (

A(x,y,z) was simplified to a function of 2 variables by Rosza Peter whose initial condition was simplified by Raphael Robinson. Ackermann was a student of David Hilbert.
