Multipole analysis in cosmic topology (1009.5825v1)
Published 29 Sep 2010 in astro-ph.CO, gr-qc, math-ph, and math.MP
Abstract: Low multipole amplitudes in the Cosmic Microwave Background CMB radiation can be explained by selection rules from the underlying multiply-connected homotopy. We apply a multipole analysis to the harmonic bases and introduce point symmetry.We give explicit results for two cubic 3-spherical manifolds and lowest polynomial degrees, and derive three new spherical 3-manifolds.
