Abstract

The behavior of baby universes has been an important ingredient in understanding and quantifying non-critical string theory or, equivalently, models of two-dimensional Euclidean quantum gravity coupled to matter. Within a regularized description based on dynamical triangulations, we amend an earlier conjecture by Jain and Mathur on the scaling behavior of genus- g surfaces containing particular baby universe 'necks', and perform a non-trivial numerical check on our improved conjecture.
