# dS / CFT correspondence on a brane

@article{Petkou2001dSC, title={dS / CFT correspondence on a brane}, author={Anastasios C. Petkou and George Siopsis}, journal={Journal of High Energy Physics}, year={2001}, volume={2002}, pages={045-045} }

We study branes moving in an AdS Schwarzschild black hole background. When the brane tension exceeds a critical value, the induced metric on the brane is of FRW type and asymptotically de Sitter. We discuss the relevance of such configurations to dS/CFT correspondence. When the black hole mass reaches a critical value that depends on the brane tension, the brane interpolates in the infinite past and future between a dS space and a finite space of zero Hubble constant. This corresponds to a…
