# COBE constraints on a compact toroidal low-density universe

@article{Inoue2000COBECO, title={COBE constraints on a compact toroidal low-density universe}, author={Kaiki Taro Inoue}, journal={Classical and Quantum Gravity}, year={2000}, volume={18}, pages={1967-1978} }

In this paper, the cosmic microwave background (CMB) anisotropy in a multiply connected compact flat 3-torus model with the cosmological constant is investigated. Using the COBE-DMR four-year data, a full Bayesian analysis revealed that the constraint on the topology of the flat 3-torus model with low matter density is less stringent. As in compact hyperbolic models, the large-angle temperature fluctuations can be produced as the gravitational potential decays at the Λ-dominant epoch well after…
