Query: Universality in the Critical Behavior of the Correlation Functions in 2d
  Simplicial Gravity   The analogue of the loop-loop correlation function in 2d gravity for the
planar connected $\phi^3$ diagrams is calculated. It is shown that although the
discretized formulas are different the scaling limit is the same as for the
loop-loop correlation function. The derivation may serve as an alternative
definition of the volume-volume correlator of Euclidean quantum gravity in
$2d$.
