Pushdown Automata and Context-Free Grammars,ext-free grammars. We then study some fundamental properties of context-free languages and we present a few basic decidability and undecidability results. We also consider the deterministic pushdown automata and the deterministic context-free languages and we present two parsing algorithms for context-free languages.

Exclaim

Decidability and Undecidability in Context-Free Languages,xt-free languages, and (iii) the linear context-free languages. We also present the Post Theorem about recursively enumerable sets, the Turing Theorem on the Halting Problem, and the Greibach Theorem about the undecidability of a property for classes of languages.

Supplementary Topics,some additional properties of finite automata, regular grammars, context-free grammars, and the so called abstract classes of languages. Finally, we present the Bernstein Theorem and we prove the existence of functions that are not computable.
