And then pop all the a's from the stack watching next no. of b's. So can be done by PDA, hence CFL. L2: First push all the a's in the stack then push all the b's in the stack. SpletFor any language L, L* must be regular If L1L2 is regular, then both L1 and L2 have to be regular. The union of finite number of regular languages is always regular.

SpletDetermine whether or not the following languages are regular. If the language is regular then give an NFA or regular expression for the language. Otherwise, use the pumping lemma for regular languages to prove the language is not regular. a) L = { anbn: n > 0} ∪ { akbm: k > 0, m > 0} b) L = { anbm: n ≤ m ≤ 2n} c) L = { 0n: n=2k for some k > 1} Splet1.1 Showing anbn non-regular We illustrate this result on the language L = {anbn: n ≥ 0}. To show the property of the corollary, it is necessary to consider all in-tegers N. This is an in nite number of cases, so the work has to be made nite by mathematics.

SpletClaim:The set L = {0n1n n ≥ 0} is not regular. Proof:… Goal: pick a string s in L of length greater than or equal to p such that any division of s as s =xyz with y >0 and xy ≤ p gives some value i≥0 with xyiz not in L Choose s = 0p1p. Consider any s = xyz with y >0, xy ≤p. Since xy ≤p, x=0m, y = 0n , z = 0r1pwith m+n+r =p, j>0. SpletFor example consider the language L = {a n b m : (n + m) is even}. For writing the regular expression we will have to consider two cases Case 1: n and m both are even Case 2: n and m are both odd. Let the regular expression for case 1 be r1, then r1 = (aa)* (bb)* (as even numbers can be represented as 2n)
