This paper investigates the computation of the eigenmodes of the Laplacian operator in multi-connected three-dimensional spherical spaces. General mathematical results and analytical solutions for lens and prism spaces are presented. Three complementary numerical methods are developed and compared with our analytic results and previous investigations. The cosmological applications of these results are discussed, focusing on the cosmic microwave background (CMB) anisotropies. In particular…

Eigenmodes of dodecahedral space
Cosmological models wherein spatial sections are the Poincare dodecahedral space D have been recently invoked to explain the missing power in the low-order angular modes of the cosmic microwave…
Laplacian eigenmodes for spherical spaces
The possibility that our space is multi–rather than singly–connected has gained renewed interest after the discovery of the low power for the first multipoles of the CMB by WMAP. To test the…
Exact polynomial eigenmodes for homogeneous spherical 3-manifolds
Observational data hint at a finite universe, with spherical manifolds such as the Poincaré dodecahedral space tentatively providing the best fit. Simulating the physics of a model universe requires…
CMB radiation in an inhomogeneous spherical space
Abstract. We analyse the CMB radiation in spherical 3-spaces with non-trivial topology. The focus is put on an inhomogeneous space which possesses observer dependent CMB properties. The suppression…
Spherical Universe topology and the Casimir effect
Recent interest in the possible non-trivial topology of the Universe, and the resulting analysis of the Laplacian eigenproblem, has prompted a reprise of calculations done by ourselves some time ago.…
Cosmic microwave background radiation in an inhomogeneous spherical space
We analyse the cosmic microwave background (CMB) radiation in spherical three-spaces with nontrivial topology. The focus is on an inhomogeneous space which possesses observer-dependent CMB…
CMB anisotropy of the poincaré dodecahedron
We analyse the anisotropy of the cosmic microwave background (CMB) for the Poincaré dodecahedron which is an example of a multi-connected spherical universe. We compare the temperature correlation…
The Spectral Action and Cosmic Topology
The spectral action functional, considered as a model of gravity coupled to matter, provides, in its non-perturbative form, a slow-roll potential for inflation, whose form and corresponding slow-roll…
Platonic topology and CMB fluctuations: homotopy, anisotropy and multipole selection rules
The cosmic microwave background (CMB) originates from an early stage in the history of the universe. Observations show low-multipole contributions of CMB fluctuations. A possible explanation is given…
Cosmic microwave background anisotropies in multiconnected flat spaces
This article investigates the signature of the seventeen multiconnected flat spaces in cosmic microwave background (CMB) maps. For each such space it recalls a fundamental domain and a set of…
