%0 Journal Article %T The AdS/CFT correspondence and Spectrum Generating Algebras %A Per Berglund %A Eric G. Gimon %A Djordje Minic %J Physics %D 1999 %I arXiv %R 10.1088/1126-6708/1999/07/025 %X We list the spectrum generating algebras for string theory and M-theory compactified on various backgrounds of the form $AdS_{d+1} \times S^n$. We identify the representations of these algebras which make up the classical supergravity spectra and argue for the presence of these spectrum generating algebras in the classical string/M-theory. We also discuss the role of the spectrum generating algebras on the conformal field theory side. %U http://arxiv.org/abs/hep-th/9905097v1
