WebThe intersection of two languages L1 and L2 is the language of all strings that are in both L1 and L2. So, for example ... L1 and L2 are accepted by finite automata, there exists a finite automaton that accepts the intersection of languages L1 and L2. We could prove this the same way we proved our hypothesis concerning complement languages, by ... WebIn contrast, while the concatenation of two context-free languages is always context-free, their intersection is not always context-free. The standard example is $\{a^nb^nc^m : n,m \geq 0\} \cap \{a^nb^mc^m : n,m \geq 0\} = \{a^nb^nc^n : n \geq 0\}$. However, the intersection of a context-free language with a regular language is always context ...
