报告摘要：

Superstring theory on AdS5xS5 has the BPS D3-brane states called giant gravitons, which corresponds to the operators with huge dimensions in N=4 super Yang-Mills. I discuss the extension of this correspondence, and propose an all-loop ansatz. On the gauge theory side, thanks to the development of finite group methods, the mixing of huge operators can be simplified to the harmonic oscillators of an effective U(p) theory, where p corresponds to the number of giant gravitons. On the string theory side, the classical equations of motion for the non-maximal giant graviton are solved perturbatively, so that the excitation spectrum remains gapless.
