I will briefly review some recent results on two-dimensional euclidean quantum gravity and minimal string theory, in both the continuum (Liouville theory)and discrete approach. Attention will be focused on how the geometry of non-compact space time (pseudosphere) may emerge from that of a compact space time (disc), for specific values of the cosmological constants.
