I don't understand the pumping lemma for this statment, can someone help me?
{a^nb^2n | n >= 0}
This is regular or not? If yes why, if no why?
Thanks to everybody!!
Language is not regular if the value of n is changed the number of states in DFA will also change.In the definition of DFA to accept regular language, the set of states is a finite set. Of course the other way to prove it as non regular ,use pumping lemma for regular languages.
