Supersymmetric large-N gauge theoriessuitable formulation for describing superstrings non-perturbatively
- non-pert. formulation of superstring/M theories e.g.) Matrix Theory (Banks-Fischler-Shenker-Susskind ’97)
IIB matrix model (Ishibashi-Kawai-Kitazawa-Tsuchiya ’97)
quantum/stringy description of black holes in terms of gauge theories
dynamical origin of space-time dimensionality, gauge group, matters, etc.
- gauge/string duality
e.g.) AdS/CFT Maldacena (’97)
Difficulty : Strongly coupled dynamics should be investigated !

Future prospects extension to lower SUSY case (Hanada-Matsuura-J.N., in progress) easier, and many things to explore
higher dimensional case possible using mass deformation (Ishiki-Kim-J.N.-Tsuchiya, in progress)
so far, planar limit important next step is to study non-planar limit Matrix theory, IIB matrix model
sign problem has to be treated carefully toy model (Anagnostopoulos-Azuma-J.N., in prep.) 6d IKKT model (Aoyama-Azuma-Hanada-J.N., in progress)
SO(6) SO(3) from Gaussian expansion (Aoyama-J.N.-Okubo, in prep.)
