Dynamics of the Cosmological Constant in Two-Dimensional Universe
arXiv:hep-th/9310059 · doi:10.1143/ptp/91.2.393
Abstract
We consider a two-dimensional model of gravity with the cosmological constant as a dynamical variable. The effective cosmological constant is derived when the universe has no initial boundary. It turns out to be extremely small if the universe is sufficiently large.
