Abstract:  
Based on the observation that AdS_{5}×S^{5}/Z_{k} orbifolds have a maximal supersymmetric PPwave limit, the description of strings in PPwaves in terms of N=2 quiver gauge theories is presented. We consider two different, small and large k, cases and show that the operators in the gauge theory which correspond to stringy excitations are labelled by two integers, the excitation and winding or momentum numbers. For the large k case, the relation between the spacetime and worldsheet deconstructions is discussed. We also comment on the possible duality between these two cases.
