Unformatted text preview: S= a k b k εL And u,v,w decomposition will have a non empty v composed entirely of ‘a’s If we pump v 0 times (uv i w  i=0), then a < b, the resulting string is not in L. So L is not regular. 4. There are two different ways that can be employed in solving this question. One can either figure out what this NFA represents and draw a minimized DFA for it, hence finding the number of equivalence classes, or convert the NFA to a DFA, minimize the result and find the number of equivalence classes that way. There are straightforward algorithms to convert an NFA to a DFA (page 178) and minimizing the DFA(pages 182188) in Sudkamp. Here we will see the second way since it is more rigorous....
