Abstract

We show that the string spectrum in the pp-wave limit of AdS5× S5/ZM (orbifolded pp-wave) is reproduced from the N=2 quiver gauge theory by quantizing the Green-Schwarz string theory on the orbifolded pp-wave in light cone gauge. We find that the twisted boundary condition on the world-sheet is naturally interpreted from the viewpoint of the quiver gauge theory. The correction of order gYM2 to the gauge theory operators agrees with the result in its dual string theory. We also discuss strings on some other orbifolded pp-waves.
