Contribution
It extends previous work by explicitly calculating cohomology rings for new cases and deriving a homotopy equivalence formula in a 7-dimensional example.
Findings
Computed cohomology rings for new Sasaki-Einstein manifolds
Derived a homotopy equivalence formula in a 7-dimensional case
Enhanced understanding of the topological classification of these manifolds
Abstract
This is a sequel to our paper arXiv:1402.2546 to appear in the Journal of Geometric Analysis 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 arXiv:1402.2546 and give a formula for homotopy equivalence in one particular 7-dimensional case.
