Giant gravitons from holomorphic surfaces

Abstract

We introduce a class of supersymmetric cycles in spacetimes of the form AdS times a sphere or T1,1 which can be considered as generalizations of the giant gravitons. Branes wrapped on these cycles preserve 1/2, 1/4 or 1/8 of the supersymmetry. On the CFT side these configurations correspond to superpositions of the large number of BPS states.
