Cheeger manifolds and the classification of biquotients
A closed manifold is called a biquotient if it is diffeomorphic to K\G/H for some compact Lie group G with closed subgroups K and H such that K acts freely on G/H. Every biquotient has a Riemannian metric of nonnegative sectional curvature. In fact, almost all known manifolds of nonnegative curvature are biquotients. The only known closed manifolds of nonnegative sectional curvature which were ...
متن کاملGeometric Formality of Homogeneous Spaces and of Biquotients
We provide examples of homogeneous spaces which are neither symmetric spaces nor real cohomology spheres, yet have the property that every invariant metric is geometrically formal. We also extend the known obstructions to geometric formality to some new classes of homogeneous spaces and of biquotients, and to certain sphere bundles.
متن کاملThe classification of simply connected biquotients of dimension at most 7 and 3 new examples of almost positively curved manifolds
We classify all compact 1-connected manifolds $M^n$ for $2 \leq n leq 7$ which are diffeomorphic to biquotients. Further, given that $M$ is diffeomorphic to a biquotient, we classify the biquotients it is diffeomorphic to. Finally, we show the homogeneous space $Sp(3)\Sp(1) \tines Sp(1)$ and two of its quotients $Sp(3)\Sp(1) \times Sp(1) \times S^1$ and $\delta S^1 \backslash Sp(3)/Sp(1)\times ...
متن کاملOn the Ricci curvature of normal metrics on Biquotients
We show that any normal metric on a closed biquotient with finite fundamental group has positive Ricci curvature.
متن کاملPsychopathology Dimensions of Females Experiencing Family Violence and a Perspective to Their Habilitation
Objectives: Violence is a widespread problem that occurs all over the word among all ages, genders, races, educational level and socio- economic groups. The aim of this study was to investigate modeling of different processes that could account for the link between experiencing spouse abuse in women and psychology, psychopathology, social and demographic factors. Methods: Data were gathere...
