IIB supergravity and various aspects of light-cone formalism in AdS space-time

Light-cone gauge manifestly supersymmetric formulation of type IIB 10-dimensional supergravity in $Ad{S}_5\times S^5$ background is discussed. The formulation is given entirely in terms of light-cone scalar superfield, allowing us to treat all component fields on an equal footing. Discrete energy spectrum of field propagating in AdS space is explained within the framework of light-cone approach. Light-cone gauge formulation of self-dual fields propagating in AdS space is developed. An conjectured interrelation of higher spin massless fields theory in AdS space-time and superstring theory in Minkowski space is discussed.
