On the topology of some Sasaki-Einstein manifolds

摘要

This is a sequel to our forthcoming paper (J. Geom. Anal., 2015)in which we concentrate on developing some of the topological properties of Sasaki-Einstein manifolds.In particular, we explicitly compute the cohomology rings for several cases not treated in that paper, and give formulae for homotopy equivalence as well as homeomorphism equivalence in one particular 7-dimensional case.
