Key Concepts

Concatenation

Concatenation in regular expressions is the operation of linking sequences of symbols or subexpressions together to form longer strings. It is fundamental in defining how patterns combine to form more complex strings.

Union Operation

The union operation, often denoted by the '+' symbol in regular expressions, represents a choice between several possibilities. It succinctly captures alternative sequences that can be part of the language.

Formal Language

A formal language is a set of strings constructed from a finite alphabet according to specific rules. In the context of regular expressions, it represents all strings that match the defined pattern, serving as a key concept in the theory of computation.

Regular Expression

A regular expression is a formal notation used to describe patterns within strings, defining formal languages by employing operators like union, concatenation, and repetition. It is essential for defining the set of strings that adhere to a specified pattern.

Kleene Star

The Kleene star is an operator in regular expressions that allows for zero or more repetitions of the preceding element. It plays a central role in describing potentially infinite sets of strings in a compact and concise way.
