Quantum Gravity in 2 + 1 Dimensions: The Case of a Closed Universe
نویسنده
چکیده
In three spacetime dimensions, general relativity drastically simplifies, becoming a "topological" theory with no propagating local degrees of freedom. Nevertheless, many of the difficult conceptual problems of quantizing gravity are still present. In this review, I summarize the rather large body of work that has gone towards quantizing (2 + 1)-dimensional vacuum gravity in the setting of a spatially closed universe.

String Bit Models of Two-Dimensional Quantum Gravity Coupled with Matter
We extend the formalism of Hamiltonian string bit models of quantum gravity type in two spacetime dimensions to include couplings to particles. We find that the single-particle closed and open universe models respectively behave like empty open and closed universes, and that a system of two distinguishable particles in a closed universe behaves like an empty closed universe. We then construct a...
متن کاملConical Singular Solutions in (2+1)-Dimensional Gravity Employing the ADM Canonical Formalism
Topological solutions in the (2+1)-dimensional Einstein theory of gravity are studied within the ADM canonical formalism. It is found that a conical singularity appears in the closed de Sitter universe solution as a topological defect in the case of the Einstein theory with a cosmological constant. Quantum effects on the conical singularity are studied using the de Broglie-Bohm interpretation. ...
متن کاملParticle creation in a toroidal universe
Although current astrophysical observations provide precise information on the geometry of the universe [1], its topology remains a mystery. We don’t even know whether the universe is compact or infinite. Nevertheless, lower bounds can be placed on its size for each compact topology (see Ref. [2] and references therein). Amongst the possible topologies for the universe, those with some or all s...
متن کاملClosed Time like Curves and the Energy Condition in 2+1 Dimensional Gravity
We consider gravity in 2+1 dimensions in presence of extended stationary sources with rotational symmetry. We prove by direct use of Einstein’s equations that if i) the energy momentum tensor satisfies the weak energy condition, ii) the universe is open (conical at space infinity), iii) there are no CTC at space infinity, then there are no CTC at all. The problem of closed time like curves (CTC...
متن کاملHierarchy and Wave Functions in a Simple Quantum Cosmology
Astrophysical observations indicate the universe is asymptotic to a de Sitter space with vacuum energy density ΩA = 0.7. Then, since H0 ≈ 65 km sec −1 Mpc, our universe has only about 10 degrees of freedom. A finite number of degrees of freedom is consistent with a closed universe arising from a quantum fluctuation, with zero total quantum numbers. If space-time has eleven dimensions, and the u...
