"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 alphabet of the language. Equivalently, a formal language is recursive if there exists a total Turing machine (a Turing machine that halts for every given input) that, when given a finite sequence of symbols as input, accepts it if it belongs to the language and rejects it … " - Recursively language

Obviously it holds: [ recursive] = [ recursive] rec. The recursive convergence criterion does not restrict the intensional one, unless the learners are recursive. The same is true for learning from ordinary texts and from informants.

From a Linguistics viewpoint, recursion can also be called nesting. As I've stated in this answer to what defines a language (third-last bullet point), recursion "is a phenomenon where a linguistic rule can be applied to the result of the application of the same rule." Let's see an example of this.

Webb16 juni 2024 · Recursion is the repeated sequential use of a particular type of linguistic element or grammatical structure. Another way to describe recursion is linguistic recursion. More simply, recursion has also been described as the ability to place one component inside another component of the same kind.

WebbHence, we only have to show that a recursive set is recursively enumerable. The empty set is recursively enumerable by deﬁnition. Otherwise, let y ∈ A be any element.
