Russkikh, N. E. On generalized 7-dimensional Seifert fibrations over complex projective plane. (Russian. English summary) Zbl 1329.53051 Sib. Èlektron. Mat. Izv. 11, 966-974 (2014). Summary: We discuss topological properties of certain 7-dimensional generalized Seifert fibrations, and, in particular, of the Eschenburg spaces with positive sectional curvature. We compute the values of the first fractional Chern class \(\kappa\) of the corresponding \(S^3/\mathbb{Z}_q\) bundles over \(\mathbb{C}P ^1\).
