Formal Languages and Automata Theory

Welcome to the world of formal languages and automata theory - the mathematical foundation of computer science and linguistic structures. This section explores the theoretical concepts that underpin programming languages, compilers, and computational models.

What Are Formal Languages?​

A formal language is a set of strings of symbols drawn from a finite alphabet. These languages are defined precisely using mathematical models and are studied in computer science for parsing, compilation, and theoretical computation.

Key Topics in Formal Language Theory​

L={w∈Σ∗∣w satisfies some condition}L = \{ w \in \Sigma^* \mid w \text{ satisfies some condition} \}

Where:

  • Σ\Sigma represents an alphabet
  • Σ∗\Sigma^* represents all possible strings over the alphabet
