In computational complexity theory, the complexity class ELEMENTARY of elementary recursive functions is the union of the classes The name was coined by László Kalmár, in the context of recursive functions and undecidability; most problems in it are far from elementary.

In mathematical logic and computer science, the μ-recursive functions are a class of partial functions from natural numbers to natural numbers that are "computable" in an intuitive sense.
This is a list of complexity classes in computational complexity theory.
PR is the complexity class of all primitive recursive functions—or, equivalently, the set of all formal languages that can be decided by such a function.

R is the eighteenth letter of the Latin alphabet.
In computability theory and computational complexity theory, RE (recursively enumerable) is the class of decision problems for which a 'yes' answer can be verified by a Turing machine in a finite amount of time.

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.
