Formal Definition of Regular Expression: Let Σ be a given alphabet. Then 1. 𝜙,𝜖, and 𝑎 ∈ Σ are all regular expression. These are called primitive regular expression. 2. If 𝑟1, 𝑟2 are regular expressions, then 𝑟1 + 𝑟2, 𝑟1. 𝑟2, 𝑟1∗ and ( 𝑟1) are also regular expressions. 3. A string is a regular expression if and only if it can be derived from the primitive regular expression by a finite number of applications of the rules in (2).
