Conformally flat semi-symmetric spaces Giovanni Calvaruso (2005) Archivum Mathematicum Similarity: We obtain the complete classification of conformally flat semi-symmetric spaces.
Three-dimensional conformally flat pseudo-symmetric spaces of constant type Norio Hashimoto, Masami Sekizawa (2000) Archivum Mathematicum Similarity: An explicit classification of the spaces in the title is given. The resulting spaces are locally products or locally warped products of the real line and two-dimensional spaces of constant curvature.
