Recently, some departures from the ΛCDM model have been reported by WMAP and Planck satellites such as suppression of the lowest CMB multipoles, and the hemispherical asymmetry in CMB anisotropy plan. It motivates us to consider models with nonzero curvature index and study the imprints of curvature and topology on the observed anomalies. So in this article we study the positively curved inflationary...
