DESCRIPTION:\n	Abstract:\n	We study perturbative cosmological correlators 
 in wavefunctionals which solve the Wheeler-DeWitt equation in asymptotical
 ly de Sitter spacetimes and were constructed in arxiv:2303.16315. Even in 
 the G_N \\rightarrow 0 limit\, it is necessary to impose the gravitational
  Gauss law\, which forces states to be de Sitter invariant. We set up Feyn
 man rules for computing cosmological correlators in such states. We enumer
 ate some necessary (but not sufficient) conditions that must be imposed on
  states and observables to avoid group-volume divergences. We provide samp
 le computations to show that such cosmological correlators can be nontrivi
 al even when the Hartle-Hawking wavefunction is Gaussian. We show that\, i
 n the presence of a heavy background state\, it is possible to construct a
  class of state-dependent relational observables that approximate correlat
 ors in the Hartle-Hawking state.\n	To attend via Zoom:https://zoom.us/j/97
