Abstract

A method developed for placing the constraints by searching for matched circles in the map on the topology of the universe was discussed. The cosmic microwave background (CMB) fluctuations that came primarily from the last scattering surface (LSS) were the key assumptions in the analysis. It was found that there were no matched circles with radius greater than 25°. It was observed that the space of the local geometry constrained but did not dictated the topology of the space. The Wilkinson microwave anisotropy probe (WMAP) data suggested that the universe was either Euclidean or its radius of curvature was large compared to the radius of the LSS.
