Description |
We derive the collective theory of large-N Sp(N) spin models and display its unconventional features. Using the known relationship between O(N) spin models and Vasiliev theory in AdS space, we argue that the unique features of the Sp(N) collective theory suggest an interpretation in terms of a higher spin theory in de Sitter space, in a manner reminiscent of the way the Liouville mode is naturally interpreted as time in supercritical string theory. |
