Summary: The aim of this thesis is to deepen understanding of the effect dielectric, and apply it to the microscopic description of gravitons giants. More specifically, the results obtained and presented in this thesis in the proposal are:. Graviton giant AdS7 x S4 and dual AdS4x S7: it is the most standard, and in both cases we must build a S2 Noncommutative. . Graviton giants and dual AdS3 x S3 x T4: a priori must build S1 not commutative, which makes no sense. We will see that in the end, with the help of a climb of T-dualidad succeed construirun cylinder not commutative. . Graviton giant and dual AdS5 x S5: although a priori we build a S3 Noncommutative, we see that we must see the S3 as a fibrado of Hopf based S2 and fiber S1. Thus, the only basis S2 is not commutative, while the U (1) Extra technically will be key in our description. . Graviton giant AdS4 x S7 and dual AdS7 x S4: very sintoníacon the last we will see that we will need to use the internal isometría in S5 that the graviton would in principle, but instead of a much more elaborate. At the end variety Noncommutative building is a CP2. Creemosque this is the first example of a CP2 not commutative physically motivated. Also will be seen in the thesis as the version of M theory proposed by Berenstein, Maldacena and Nastase in 2002 on the edge of Penrose of AdS in 11 dimensions can be obtained as part of the effort to limit overlapping gravitons. Using this fact in the thesis will be discussed first microscopic description of invariant vacuum SO (6) of this theory.
