Use the Pumping Lemma to show that the following languages are not regular.
(a){apaq | for all integers p and q where q is a prime number and p is not prime}.
(b) {ai bj || i − j | = 3}
(c) {ai bj ck | i = j or j 6= k}
(d) {aibj | i/j is an integer}
I'll add them in few minutes! Please wait..

Use the pumping lemma to show that each of the following languages is not regular. L = {0i 1j 0k |k > i + j} Not entierly sure what to do when there are 3 variables.
Can someone use pumping Lemma to show if these are regular languages or not c) Is L regular? give a finite automaton or prove using pumping lemma. (d) Is L context-free? give a context-free grammar or pushdown automaton, otherwise pr using pumping lemma. (16 pts)Given the set PRIMES (aP | p is prime (a) Prove that PRIMES is not regular. (b) Prove that PRIMES is not context-free. (c) Show if complement of PRIMES (PRIMES ) is regular or not. d)...
The pumping lemma for regular languages is Theorem 1.70 on page 78 of the required text. Definition: w is a string if and only if there exists an alphabet such that w is a string over that alphabet. Note: For every alphabet, the empty string is a string over that alphabet. Notation: For any symbol o, gº denotes the empty string, and for every positive integer k, ok denotes the string of length k over the alphabet {o}. 1) (20%]...
Use the pumping lemma for regular languages to carefully prove that the language { aibjck : 0≤ i < j < k } is not regular.
Pumping lemma s. (7+5 points) Pumping lemma for regular languages. In all cases, -a,b) a) Consider the following regular language A. ping length p 2 1. For each string s e pumping lemma, we can write s -xy, with lyl S p, and s can be pumped. Since A is regular, A satisfies the pumping lemma with pum A, where Is] 2 p, by the a) Is p 3 a pumping length for language 4? (Yes/No) b) Show that w...
