Query: Primordial fluctuations in extended Liouville theory   Liouville gravity can be used to precisely model features of 3+1 dimensional
cosmology in a simplified 1+1d setting. We study primordial fluctuations in a
generally covariant extension of Liouville theory, in the context of single
field inflation. The scale invariant spectrum of scalar curvature perturbations
is exhibited, and their three-point correlation function is computed in the
slow roll approximation. We recover Maldacena's consistency relation for the
three-point function, which in this context depends on a global shift symmetry
of extended Liouville theory.
