The Kleene Star is an operation in formal language theory that allows for the creation of new languages by taking the set of all possible strings that can be formed by concatenating zero or more copies of a given set of strings. This operation is crucial for defining regular languages, as it enables the representation of patterns that can repeat any number of times, including not at all. The Kleene Star connects with fundamental concepts such as alphabets and languages by demonstrating how simple elements can generate complex structures.
