Regular Expressions

Regular Expressions are used to denote regular languages. An expression is regular if:

ɸ is a regular expression for regular language ɸ.

ɛ is a regular expression for regular language {ɛ}.

If a ∈ Σ (Σ represents the input alphabet), a is regular expression with language {a}.

If a and b are regular expression, a + b is also a regular expression with language {a,b}.

If a and b are regular expression, ab (concatenation of a and b) is also regular.

If a is regular expression, a* (0 or more times a) is also regular.
