dc.descriptionWe analyze two models of random geometries~: planar hyper-cubic random surfaces and four dimensional simplicial quantum gravity. We show for the hyper-cubic random surface model that a geometrical constraint does not change the critical properties of the model compared to the model without this constraint. We analyze the phase diagram for the model with extrinsic curvature. For four dimensional simplicial quantum gravity we find that in the large volume limit the leading contribution to the entropy does not depend on the underlying topology. We find for the first time a strong back-reaction of the geometric sector for matter coupled to gravity.
