Some new examples with almost positive curvature

Kerin, Martin (2011) 'Some new examples with almost positive curvature.', Geometry & Topology, 15 (1). pp. 217-260.


As a means to better understanding manifolds with positive curvature, there has been much recent interest in the study of nonnegatively curved manifolds which contain points at which all 2 –planes have positive curvature. We show that there are generalisations of the well-known Eschenburg spaces and quotients of S 7 × S 7 which admit metrics with this property.
