Mathematically, a set of mutually recursive functions are primitive recursive, which can be proven by course-of-values recursion, building a single function F that lists the values of the individual recursive function in order: = (), (), (), (), …, and rewriting the mutual recursion as a primitive recursion. Any mutual recursion between two ...
In computability theory, Bekić's theorem or Bekić's lemma is a theorem about fixed-points which allows splitting a mutual recursion into recursions on one variable at a time. [1] [2] [3] It was created by Austrian Hans Bekić (1936-1982) in 1969, [4] and published posthumously in a book by Cliff Jones in 1984. [5] The theorem is set up as ...

In computer science, corecursion is a type of operation that is dual to recursion.Whereas recursion works analytically, starting on data further from a base case and breaking it down into smaller data and repeating until one reaches a base case, corecursion works synthetically, starting from a base case and building it up, iteratively producing data further removed from a base case.
MIT OpenCourseWare is supported by MIT, corporate underwriting, major gifts, and donations from site visitors. [2] The initiative inspired a number of other institutions to make their course materials available as open educational resources. [3] As of May 2018, over 2,400 courses were available online.
The terminology, syntax and semantics vary from language to language. In Scheme, let is used for the simple form and let rec for the recursive form. In ML let marks only the start of a block of declarations with fun marking the start of the function definition. In Haskell, let may be mutually recursive, with the compiler figuring out what is ...

More expressive fragments are defined for any k > 0 by mutual recursion: + has the form …, where is a formula, and similar, + has the form …, where is a formula. (See analytical hierarchy for the analogous construction of second-order arithmetic .)
