The string susceptibility exponents for the boundary surfaces in three-dimensional DT mfds are measured numerically. For spherical boundary surfaces, we obtain a result consistent with the case of a two-dimensional spherical DT surface described by the matrix model. This gives a correct method to reconstruct two-dimensional random surfaces from three-dimensional DT mfds. Furthermore, a scaling property of the volume distribution of minimum neck baby universes is investigated numerically in the case of three and four dimensions, and we obtain a common scaling structure near to the critical points belonging to the strong coupling phase in both dimensions. We have evidence for the existence of a common fractal structure in three- and four-dimensional simplicial quantum gravity.}, pages = {97--104}, title = {Common structures in simplicial quantum gravity}, volume = {459}, year = {1992} }
