The class of recursive language is known as
網頁The class of recursively enumerable languages is not closed under complementation, because there are examples of recursively enumerable languages whose complement is not recursively enumerable. Those examples come from languages that are recursively enumerable, but not recursive. The class of all recursive languages is often called R, although this name is also used for the class RP. This type of language was not defined in the Chomsky hierarchyof (Chomsky 1959). All recursive languages are also recursively enumerable. All regular, context-freeand context-sensitivelanguages are recursive. … 查看更多內容 In mathematics, logic and computer science, a formal language (a set of finite sequences of symbols taken from a fixed alphabet) is called recursive if it is a recursive subset of the set of all possible finite sequences over the … 查看更多內容 Recursive languages are closed under the following operations. That is, if L and P are two recursive languages, then the following languages are recursive as well: • The Kleene star $${\displaystyle L^{*}}$$ • The image φ(L) under an e-free homomorphism 查看更多內容 There are two equivalent major definitions for the concept of a recursive language: 1. A recursive formal language is a recursive 查看更多內容 As noted above, every context-sensitive language is recursive. Thus, a simple example of a recursive language is the set L={abc, aabbcc, aaabbbccc, ...}; more formally, the set is context-sensitive and therefore recursive. 查看更多內容 • Recursively enumerable language • Computable set • Recursion 查看更多內容

The following table summarizes each of Chomsky's four types of grammars, the class of language it generates, the type of automaton that recognizes it, and the form its rules must have. Note that the set of grammars corresponding to recursive languages is not a member of this hierarchy; these would be properly between Type-0 and Type-1. 網頁2015年11月2日 · We recall the definition of a recursively enumerable languages as: A RE language is a language such that there exists a Turing machine that halts on every member of the language with a yes output, and possibly runs forever on non-members So we just take a Turing machine that simulates another Turing machine ( universal Turing machine ).

For a deeper look, we have to delve into the arithmetical hierarchy. We can write L symbolically as follows: L = { M : ∀ t M doesn't halt within t steps }.

Example When a Turing machine reaches a final state, it halts. We can also say that a Turing machine M halts when M reaches a state q and a current symbol ‘a’ to be scanned so that δ (q, a) is undefined.
