Pumping Lemma for Regular Languages

We show that L = { uu | u∈{a,b} * } is not regular. Let n be the pumping constant. Then we choose w=a. n. ba. n. b which clearly has length greater than n. The initial string a. n . must contain the pump, u. So w = xuyba. n. b, and xuyb = a. n. b. But pumping u 0 times it must be the case that xyba. n. b is in L too. But since u is not ε, we
