CDT and Horava-Lifshitz QG in Two Dimensions
Abstract
The two-dimensional causal dynamical triangulations (2d CDT) is a lattice model of quantum geometry. In 2d CDT, one can deal with the quantum effects analytically and explore the physics through the continuum limit. The continuum theory is known to be two-dimensional projectable Horava-Lifshitz quantum gravity (2d projectable HL QG). In this chapter, we wish to review the very relation between 2d CDT and 2d projectable HL QG in detail.
