Nonnegative curvature, low cohomogeneity and complex cohomology

We construct several infinite families of nonnegatively curved manifolds of low cohomogeneity and small dimension which can be distinguished by their cohomology rings. In particular, we exhibit an infinite family of eight-dimensional cohomogeneity one manifolds of nonnegative curvature with pairwise nonisomorphic complex cohomology rings.
