How do you prove that regular languages are closed under?
Regular languages are closed under inverse homomorphism, i.e., if L is regular and h is a homomorphism then h−1(L) is regular.
Intuition: On input w M will run M on h(w) and accept if M does.
Intuition: On input w M will run M on h(w) and accept if M does.Well, we have A스B = (A<B)U(B<A), and since we've seen that regular languages are closed under set difference and under unions, it follows that regular languages are also closed under symmetric difference.
Are regular languages closed under substring operation?
1 Answer. substrings property is not closed under regular languages. suppose substrings for the above language L={ab,aabb,aaabbb,.} it is not regular language.
Is the regular language closed under concatenation operation?
Regular languages are closed under concatenation - this is demonstrable by having the accepting state(s) of one language with an epsilon transition to the start state of the next language.
If we consider the language L = {a^n n >=0}, this language is regular (it is simply a*).
