摘要
Single trace operators with the large R-charge in supersymmetric Yang-Mills theory correspond to the null-surfaces in . We argue that the moduli space of the null-surfaces is the space of contours in the super-Grassmanian parametrizing the complex -dimensional subspaces of the complex -dimensional space. The odd coordinates on this super-Grassmanian correspond to the fermionic degrees of freedom of the superstring.
