1. Superstring theory -- what is it?

2. Superstring theory, chaos math, advanced algorithms.

3. And Ed Witten unleashed the second superstring revolution.

4. Supergravity, as the low energy limit of superstring theory, offered the proper set-up to accommodate cosmic inflation.

5. The supergravity and superstring theories in which Branes play promi-nent roles are generalizations of

6. D-Branes represent a key theoretical tool in the understanding of strongly coupled superstring theory and M-theory

7. 13 The dynamic model of phase transition in string cosmology is studied in this paper. The superstring phase transition and QCD phase transition in early universe are analysed.

8. One can focus on the "near-horizon" geometry of the black 3-Branes, for example and it looks like five-dimensional anti de Sitter space (5 is 3+1+1, where 3 spatial dimensions come from the 3-Branes, 1 is time, and the last 1 is the radial dimension) multiplied by a five-dimensional sphere, and type IIB superstring theory lives there.
