Abstract	Formal language theory as a discipline is generally regarded as growing from the work of linguist Noam Chomsky in the 1950s, when he attempted to give a precise characterization of the structure of natural languages. His goal was to define the syntax of languages using simple and precise mathematical rules. Later it was found that the syntax of programming languages can be described using one of Chomsky’s grammatical models called context-free grammars. Much earlier, the Norwegian mathematician Axel Thue studied sequences of binary symbols subject to interesting mathematical properties, such as not having the same substring three times in a row. His work influenced Emil Post, Stephen Kleene, and others to study the mathematical properties of strings and collections of strings. Soon after the advent of modern electronic computers, people realized that all forms of information—whether numbers, names, pictures, or sound waves—can be represented as strings. Then collections of strings known as languages became central to computer science. This section is concerned with fundamental mathematical properties of languages and language generating systems, such as grammars. Every programming language from Fortran to Java can be precisely
