WebProve that regular languages are closed under intersection. That is, given two regular languages L 1 and L 2, prove that L 1 ∩ L 2 is regular. Proof via closure under complement and union Note that L 1 ∩ L 2 =L 1∪ L 2 We previously proved (in lecture and in the textbook) that languages are closed under complement and union. Thus Web• Once we have defined languages formally, we can consider combinations and modifications of those languages: – unions, intersections, complements, and so on. • …

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 $\{a^nb^nc^m : n,m \geq 0\} \cap \{a^nb^mc^m : n,m \geq 0\} = \{a^nb^nc^n : n \geq 0\}$.

WebRemark 1: If we have NFA rather than DFA, we must first convert it to DFA before swapping states to get its complement. Remark 2: Since a language is regular if and only if it is accepted by some NFA, the complement of a regular language is also regular. Intersection of Regular Languages Langauges are sets.

WebJun 15, 2024 · L1 = {0*1*} is a regular language and. L2 = {0^n1^n n>=0} is a CFL. The intersection of two languages is as follows −. L= L1 ∩ L2. It results in the following −. L= {0^n1^n n>=0} which is context-free . So, finally it is concluded that the intersection of regular language and context free language generates a context free language.
